-Announce: Release of PyGreSQL version 3.3
-=========================================
-
-PyGreSQL v3.3 has been released.
-It is available at: ftp://ftp.druid.net/pub/distrib/PyGreSQL.tgz.  If
-you are running NetBSD, look in the packages directory under databases.
-There is also a package in the FreeBSD ports collection.              
-
-From March 1 2001 the PyGreSQL development has moved into the PostgreSQL
-development tree.
-
-PostgreSQL is a database system derived from Postgres4.2. It conforms
-to (most of) ANSI SQL and offers many interesting capabilities (C
-dynamic linking for functions or type definition, etc.). This package
-is copyright by the Regents of the University of California, and is
-freely distributable.
-
-Python is an interpreted programming language. It is object oriented,
-simple to use (light syntax, simple and straightforward statements), and
-has many extensions for building GUIs, interfacing with WWW, etc.  An
-intelligent web  browser (HotJava like) is currently under development
-(November 1995), and this should open programmers many doors. Python is
-copyrighted by Stichting S Mathematisch Centrum, Amsterdam, The
-Netherlands, and is freely distributable.
-
-PyGreSQL is a python module that interfaces to a PostgreSQL database. It
-embeds the PostgreSQL query library to allow easy use of the powerful
-PostgreSQL features from a Python script.
-
-This release fixes a few bugs, adds a few minor features and makes a
-few speedups in the code.
-
-The next release (unless serious bugs are found) will be to match PyGreSQL
-to version 2.0 of Python.
-
-See the other changes below or in the Changelog file.
-
-PyGreSQL 2.0 was developed and tested on a NetBSD 1.3_BETA system.  It
-is based on the PyGres95 code written by Pascal Andre,
-andre@chimay.via.ecp.fr.  I changed the version to 2.0 and updated the
-code for Python 1.5 and PostgreSQL 6.2.1.  While I was at it I upgraded
-the code to use full ANSI style prototypes and changed the order of
-arguments to connect.  Later versions are fixes and enhancements to that.
-The latest version of PyGreSQL works with Python 1.5.2 and PostgreSQL 7.0.x
-
-Important changes from PyGreSQL 3.2 to PyGreSQL 3.3
-  - Added NUMERICOID to list of returned types.  This fixes a bug when
-    returning aggregates in the latest version of PostgreSQL.
-
-Important changes from PyGreSQL 3.1 to PyGreSQL 3.2
-  Note that there are very few changes to PostgreSQL between 3.1 and
-  3.2.  The main reason for the release is the move into the PostgreSQL
-  development tree.  Even the WIN32 changes are pretty minor.
-  - Add WIN32 support (gerhard@bigfoot.de)
-  - Fix some DB-API quoting problems (niall.smart@ebeon.com)
-  - Moved development into PostgreSQL development tree.
-
-Important changes from PyGreSQL 3.0 to PyGreSQL 3.1
-  - Fix some quoting functions.  In particular handle NULLs better.
-  - Use a method to add primary key information rather than direct
-    manipulation of the class structures.
-  - Break decimal out in _quote (in pg.py) and treat it as float.
-  - Treat timestamp like date for quoting purposes.
-  - Remove a redundant SELECT from the get method speeding it, and insert
-    since it calls get, up a little.
-  - Add test for BOOL type in typecast method to pgdbTypeCache class.
-    (tv@beamnet.de)
-  - Fix pgdb.py to send port as integer to lower level function
-    (dildog@l0pht.com)
-  - Change pg.py to speed up some operations
-  - Allow updates on tables with no primary keys.
-
-Important changes from PyGreSQL 2.4 to PyGreSQL 3.0:
-  - Remove strlen() call from pglarge_write() and get size from object.
-    (Richard@Bouska.cz)
-  - Add a little more error checking to the quote function in the wrapper
-  - Add extra checking in _quote function
-  - Wrap query in pg.py for debugging
-  - Add DB-API 2.0 support to pgmodule.c (andre@via.ecp.fr)
-  - Add DB-API 2.0 wrapper pgdb.py (andre@via.ecp.fr)
-  - Correct keyword clash (temp) in tutorial
-  - Clean up layout of tutorial
-  - Return NULL values as None (rlawrence@lastfoot.com) (WARNING: This
-    will cause backwards compatibility issues.)
-  - Change None to NULL in insert and update
-  - Change hash-bang lines to use /usr/bin/env
-  - Clearing date should be blank (NULL) not TODAY
-  - Quote backslashes in strings in _quote (brian@CSUA.Berkeley.EDU)
-  - Expanded and clarified build instructions (tbryan@starship.python.net)
-  - Make code thread safe (Jerome.Alet@unice.fr)
-  - Add README.distutils (mwa@gate.net & jeremy@cnri.reston.va.us)
-  - Many fixes and increased DB-API compliance by chifungfan@yahoo.com,
-    tony@printra.net, jeremy@alum.mit.edu and others to get the final
-    version ready to release.
-
-Important changes from PyGreSQL 2.3 to PyGreSQL 2.4:
-  - Insert returns None if the user doesn't have select permissions
-    on the table.  It can (and does) happen that one has insert but
-    not select permissions on a table.
-  - Added ntuples() method to query object (brit@druid.net)
-  - Corrected a bug related to getresult() and the money type
-  - Corrected a bug related to negative money amounts
-  - Allow update based on primary key if munged oid not available and
-    table has a primary key
-  - Add many __doc__ strings. (andre@via.ecp.fr)
-  - Get method works with views if key specified
-
-Important changes from PyGreSQL 2.2 to PyGreSQL 2.3:
-  - connect.host returns "localhost" when connected to Unix socket
-    (torppa@tuhnu.cutery.fi)
-  - Use PyArg_ParseTupleAndKeywords in connect() (torppa@tuhnu.cutery.fi)
-  - fixes and cleanups (torppa@tuhnu.cutery.fi)
-  - Fixed memory leak in dictresult() (terekhov@emc.com)
-  - Deprecated pgext.py - functionality now in pg.py
-  - More cleanups to the tutorial
-  - Added fileno() method - terekhov@emc.com (Mikhail Terekhov)
-  - added money type to quoting function
-  - Compiles cleanly with more warnings turned on
-  - Returns PostgreSQL error message on error
-  - Init accepts keywords (Jarkko Torppa)
-  - Convenience functions can be overridden (Jarkko Torppa)
-  - added close() method
-
-Important changes from PyGreSQL 2.1 to PyGreSQL 2.2:
-  - Added user and password support thanks to Ng Pheng Siong <ngps@post1.com>
-  - Insert queries return the inserted oid
-  - Add new pg wrapper (C module renamed to _pg)
-  - Wrapped database connection in a class.
-  - Cleaned up some of the tutorial.  (More work needed.)
-  - Added version and __version__.  Thanks to thilo@eevolute.com for
-    the suggestion.
-
-Important changes from PyGreSQL 2.0 to PyGreSQL 2.1:
-  - return fields as proper Python objects for field type
-  - Cleaned up pgext.py
-  - Added dictresult method
-
-Important changes from Pygres95 1.0b to PyGreSQL 2.0:
-  - Updated code for PostgreSQL 6.2.1 and Python 1.5.
-  - Reformatted code and converted to ANSI .
-  - Changed name to PyGreSQL (from PyGres95.)
-  - Changed order of arguments to connect function.
-  - Created new type pgqueryobject and moved certain methods to it.
-  - Added a print function for pgqueryobject
-  - Various code changes - mostly stylistic.
-

-
-Version 3.3
-  A few cleanups.  Mostly there was some confusion about the latest version
-  and so I am bumping the number to keep it straight.

-    manipulation of the class structures.
-  - Break decimal out in _quote (in pg.py) and treat it as float.
-  - Treat timestamp like date for quoting purposes.
-  - Remove a redundant SELECT from the get method speeding it, and insert
-    since it calls get, up a little.
-  - Add test for BOOL type in typecast method to pgdbTypeCache class.
-    (tv@beamnet.de)
-  - Fix pgdb.py to send port as integer to lower level function

-
-1. Presentation
-===============
-
-1.1. Introduction
------------------
-
-PostgreSQL is a database system derived from Postgres4.2. It conforms to
-(most of) ANSI SQL and offers many interesting capabilities (C dynamic linking
-for functions or type definition, etc.). This package is copyright by the
-Regents of the University of California, and is freely distributable.
-
-Python is an interpreted programming language. It is object oriented, simple
-to use (light syntax, simple and straightforward statements), and has many
-extensions for building GUIs, interfacing with WWW, etc. An intelligent web
-browser (HotJava like) is currently under development (November 1995), and
-this should open programmers many doors. Python is copyrighted by Stichting S
-Mathematisch Centrum, Amsterdam, The Netherlands, and is freely distributable.
-
-PyGreSQL is a python module that interfaces to a PostgreSQL database. It
-embeds the PostgreSQL query library to allow easy use of the powerful
-PostgreSQL features from a Python script.
-
-PyGreSQL 2.0 was developed and tested on a NetBSD 1.3_BETA system.  It is
-based on the PyGres95 code written by Pascal Andre, andre@chimay.via.ecp.fr.
-I changed the version to 2.0 and updated the code for Python 1.5 and
-PostgreSQL 6.2.1.  While I was at it I upgraded the code to use full ANSI 
-style prototypes and changed the order of arguments to connect.  The latest
-version of PyGreSQL works with PostgreSQL 7.1.3 and Python 2.1.
-
-
-1.2. Distribution files
------------------------
-
-  README       - this file
-  Announce     - announcement of this release
-  ChangeLog    - changes that affected this package during its history
-  pgmodule.c   - the C python module
-  pg.py        - PyGreSQL DB class.
-  pgdb.py      - DB-SIG DB-API 2.0 compliant API wrapper for PygreSQL
-  tutorial/    - demos directory
-                 Content: basics.py, syscat.py, advanced.py, func.py and
-                 pgtools.py.  The samples here have been taken from the
-                 PostgreSQL manual and were used for module testing.  They
-                 demonstrate some PostgreSQL features.  Pgtools.py is an
-                 add-in used for demonstration.
-
-1.3. Installation
------------------
-
-* If you are building this from source on most systems you can simply add
-  the flag "--with-python" to the Configure command when building PostgreSQL.
-  This will cause PyGreSQL to be built at the same time.  For this to work
-  you must already have built Python as well as the mxDateTime package
-  from http://starship.python.net/~lemburg/mxDateTime.html.
-
-* For Linux installation look at README.linux.  If you're on an x86 system 
-  that uses RPMs, then you can pick up an RPM at 
-  ftp://ftp.druid.net/pub/distrib/pygresql.i386.rpm
-
-* Note that if you are using the DB-API module you must also install
-  mxDateTime from http://starship.python.net/~lemburg/mxDateTime.html.
-
-* Also, check out setup.py for an alternate method of installing the package.
-
-You have two options.  You can compile PyGreSQL as a stand-alone module 
-or you can build it into the Python interpreter.
-
-GENERAL 
-
-* You must first have installed Python and PostgreSQL on your system.
-  The header files and developer's libraries for both Python and PostgreSQL
-  must be installed on your system before you can build PyGreSQL.  If you 
-  built both Python and PostgreSQL from source, you should be fine.  If your 
-  system uses some package mechanism (such as RPMs or NetBSD packages), then 
-  you probably need to install packages such as Python-devel in addition to 
-  the Python package.
-
-* PyGreSQL is implemented as three parts, a C module labeled _pg and two
-  Python wrappers called pg.py and pgdb.py.  This changed between 2.1 and
-  2.2 and again in 3.0.  These changes should not affect any existing
-  programs but the installation is slightly different.
-
-* Download and unpack the PyGreSQL tarball if you haven't already done so.
-
-STAND-ALONE
-
-* In the directory containing pgmodule.c, run the following command
-  cc -fpic -shared -o _pg.so -I[pyInc] -I[pgInc] -L[pgLib] -lpq pgmodule.c
-  where:
-    [pyInc] = path of the Python include (usually Python.h)
-    [pgInc] = path of the PostgreSQL include (usually postgres.h)
-    [pgLib] = path of the PostgreSQL libraries (usually libpq.so or libpq.a)
-  Some options may be added to this line:
-    -DNO_DEF_VAR  - no default variables support
-    -DNO_DIRECT   - no direct access methods
-    -DNO_LARGE    - no large object support
-    -DNO_SNPRINTF - if running a system with no snprintf call
-    -DNO_PQSOCKET - if running an older PostgreSQL
-
-  On some systems you may need to include -lcrypt in the list of libraries
-  to make it compile.
-
-  Define NO_PQSOCKET if you are using a version of PostgreSQL before 6.4
-  that does not have the PQsocket function.  The other options will be
-  described in the next sections.
-
-* Test the new module.  Something like the following should work.
-  
-  $ python
-
-  >>> import _pg
-  >>> db = _pg.connect('thilo','localhost')
-  >>> db.query("INSERT INTO test VALUES ('ping','pong')")
-  18304
-  >>> db.query("SELECT * FROM test")
-  eins|zwei
-  ----+----
-  ping|pong
-  (1 row)
-
-* Finally, move the _pg.so, pg.py, and pgdb.py to a directory in your 
-  PYTHONPATH.  A good place would be /usr/lib/python1.5/site-python if
-  your Python modules are in /usr/lib/python1.5.
-
-BUILT-IN TO PYTHON INTERPRETER
-
-* Find the directory where your 'Setup' file lives (usually ??/Modules) in 
-  the Python source hierarchy and copy or symlink the 'pgmodule.c' file there.
-
-* Add the following line to your Setup file
-    _pg  pgmodule.c -I[pgInc] -L[pgLib] -lpq # -lcrypt # needed on some systems
-  where:
-    [pgInc] = path of PostgreSQL include (often /usr/local/include/python1.5)
-    [pgLib] = path of the PostgreSQL libraries (often /usr/local/lib/python1.5)
-  Some options may be added to this line:
-    -DNO_DEF_VAR  - no default variables support
-    -DNO_DIRECT   - no direct access methods
-    -DNO_LARGE    - no large object support
-    -DNO_SNPRINTF - if running a system with no snprintf call
-    -DNO_PQSOCKET - if running an older PostgreSQL
-
-  Define NO_PQSOCKET if you are using a version of PostgreSQL before 6.4
-  that does not have the PQsocket function.  The other options will be
-  described in the next sections.
-
-* If you want a shared module, make sure that the "*shared*" keyword is
-  uncommented and add the above line below it.  You used to need to install
-  your shared modules with "make sharedinstall but this no longer seems
-  to be true."
-
-* Copy pg.py to the lib directory where the rest of your modules are. For
-  example, that's /usr/local/lib/Python on my system.
-
-* Rebuild Python from the root directory of the Python source hierarchy by 
-  running 'make -f Makefile.pre.in boot' and 'make && make install'
-
-* For more details read the documentation at the top of Makefile.pre.in

-
-2. Programming information
-==========================
-
-You may either choose to use the old, mature interface provided by the
-'pg' module or else the newer 'pgdb' interface compliant with DB-API 2.0
-specification developed by the Python DB-SIG.
-
-The remainder of this chapter and the next chapter describe only
-the older 'pg' API.  As long as PyGreSQL does not contain a
-description of the DB-API you should read about the API at
-http://www.python.org/topics/database/DatabaseAPI-2.0.html
-
-A tutorial like introduction to the DB-API can be found at
-http://www2.linuxjournal.com/lj-issues/issue49/2605.html
-
-The 'pg' module defines three objects: the pgobject that handles the connection
-and all the requests to the database, the pglargeobject that handles
-all the accesses to Postgres large objects and pgqueryobject that handles
-query results.
-
-If you want to see a simple example of the use of some of these functions,
-see http://www.druid.net/rides/ where I have a link at the bottom to the
-actual Python code for the page.
-
-2.1. pg module description
-----------------------------
-
-The module defines only a few methods that allow to connect to a database and
-to allow to define "default variables" that override the environment variables
-used by PostgreSQL. 
-
-These "default variables" were designed to allow you to handle general 
-connection parameters without heavy code in your programs. You can prompt the
-user for a value, put it in the default variable, and forget it, without 
-having to modify your environment. The support for default variables can be
-disabled by setting the -DNO_DEF_VAR option in the Python Setup file. Methods
-relative to this are specified by te tag [DV].
-
-All variables are set to None at module initialization, specifying that 
-standard environment variables should be used.
-
-  2.1.1. connect - opens a pg connection
-  ----------------------------------------
-
-  Syntax:      
-    connect(dbname, host, port, opt, tty, user, passwd)
-  Parameters: 
-    dbname        - name of connected database (string/None)
-    host          - name of the server host (string/None)
-    port          - port used by the database server (integer/-1)
-    opt           - connection options (string/None)
-    tty           - debug terminal (string/None)
-	user          - PostgreSQL user (string/None)
-    passwd        - password for user (string/None)
-  Return type:
-    pgobject      - the object handling the connection
-  Exceptions raised:
-    TypeError     - bad argument type, or too many arguments
-    SyntaxError   - duplicate argument definition 
-    pg.error      - some error occurred during pg connection definition
-    (+ all exceptions relative to object allocation)
-  Description:
-    This method opens a connection to a specified database on a given
-    PostgreSQL server. You can use keywords here, as described in the
-    Python tutorial; 
-    the names of the keywords are the name of the parameters given in the 
-    syntax line. For a precise description of the parameters, please refer to 
-    the PostgreSQL user manual.

-
-  The following methods return information about the current connection.
-
-  - 
-2.2. pgobject description

-
-  This object handle a connection to a PostgreSQL database. It embeds and 
-hides all the parameters that define this connection, thus just leaving really
-significant parameters in function calls.
-  Some methods give direct access to the connection socket. They are specified
-by the tag [DA]. DO NOT USE THEM UNLESS YOU REALLY KNOW WHAT YOU ARE DOING. If
-you prefer disabling them, set the -DNO_DIRECT option in the Python Setup file.
-  Some other methods give access to large objects (refer to PostgreSQL user
-manual for more information about these). if you want to forbid access to these
-from the module, set the -DNO_LARGE option in the Python Setup file. These 
-methods are specified by the tag [LO].

-
-2.3. pglarge description
---------------------------
-
-  This object handles all the request concerning a postgres large object. It 
-embeds and hides all the 'recurrent' variables (object oid and connection), 
-exactly in the same way pgobjects do, thus only keeping significant 
-parameters in function calls. It keeps a reference to the pgobject used for
-its creation, sending requests though with its parameters. Any modification but
-dereferencing the pgobject will thus affect the pglarge object. 
-Dereferencing the initial pgobject is not a problem since Python won't 
-deallocate it before the large object dereference it.
-  All functions return a generic error message on call error, whatever the 
-exact error was. The 'error' attribute of the object allow to get the exact 
-error message.

-  pgcnx              - the pgobject associated with the object
-  error              - the last warning/error message of the connection
-BE CAREFUL:  in multithreaded environments, 'error' may be modified by another
-thread using the same pgobject. Remember these object are shared, not 
-duplicated. You should provide some locking to be able if you want to check 
-this.
-  The oid attribute is very interesting because it allow you reuse the oid 
-later, creating the pglarge object with a pgobject getlo() method call.
-
-
-3. The pg wrapper
-================
-
-The previous functions are wrapped in a module called pg.  The module
-has a class called DB.  The above functions are also included in the
-name space so it isn't necessary to import both modules.  The preferred
-way to use this module is as follows.
-
-import pg
-db = pg.DB(...) # See description of the initialization method below.
-
-The following describes the methods and variables of this class.
-
-
- 3.1. Initialization
- -------------------
- The DB class is initialized with the same arguments as the connect
- method described in section 2.  It also initializes a few internal
- variables.  The statement 'db = DB()' will open the local database
- with the name of the user just like connect() does.
-
- 3.2. pkey
- ---------
- Syntax:
-   pkey(table)
- Parameters:
-   table - name of table
- Returns:
-   Name of field which is the primary key of the table.
- Description:
-   This method returns the primary key of a table.  Note that this raises
-   an exception if the table doesn't have a primary key.
-
- 3.3. get_databases - get list of databases in the system
- --------------------------------------------------------
- Syntax: get_databases()
- Parameters: none
- Returns: list of databases in the system
- Description:
-   Although you can do this with a simple select, it is added here for
-   convenience
-
- 3.4. get_tables - get list of tables in connected database
- ----------------------------------------------------------
- Syntax: get_tables() 
- Parameters: none
- Returns: list of tables in connected database
-
- 3.5. get_attnames
- -----------------
- Syntax: 
-   get_attnames(table)       
- Parameters: 
-   table - name of table
- Returns:
-   Dictionary of attribute names (the names are the keys, the values
-   are the names of the attributes' types)
- Description:
-   Given the name of a table, digs out the set of attribute names.
-
- 3.6. get - get a tuple from a database table
- --------------------------------------------
- Syntax: 
-   get(table, arg, [keyname])
- Parameters:
-   table - name of table
-   arg - either a dictionary or the value to be looked up
-   keyname - name of field to use as key (optional)
- Returns:
-   A dictionary mapping attribute names to row values.
- Description:
-   This method is the basic mechanism to get a single row.  It assumes
-   that the key specifies a unique row.  If keyname is not specified
-   then the primary key for the table is used.  If arg is a dictionary
-   then the value for the key is taken from it and it is modified to
-   include the new values, replacing existing values where necessary.
-   The oid is also put into the dictionary but in order to allow the
-   caller to work with multiple tables, the attribute name is munged
-   to make it unique.  It consists of the string "oid_" followed by
-   the name of the table.
-
-
- 3.7. insert - insert a tuple into a database table
- --------------------------------------------------
- Syntax:
-   insert(table, a)
- Parameters:
-   table - name of table
-   a - a dictionary of values
- Returns:
-   The OID of the newly inserted row.
- Description:
-   This method inserts values into the table specified filling in the
-   values from the dictionary.  It then reloads the dictionary with the
-   values from the database.  This causes the dictionary to be updated
-   with values that are modified by rules, triggers, etc.
-
-   Due to the way that this function works you will find inserts taking
-   longer and longer as your table gets bigger.  To overcome this problem
-   simply add an index onto the OID of any table that you think may get
-   large over time.
-
-
- 3.8. update
- -----------
- Syntax:
-   update(table, a)             
- Parameters:
-   table - name of table
-   a - a dictionary of values
- Returns:
-   A dictionary with the new row
- Description:
-   Similar to insert but updates an existing row.  The update is based
-   on the OID value as munged by get.  The array returned is the
-   one sent modified to reflect any changes caused by the update due
-   to triggers, rules, defaults, etc.
-
- 3.9. clear
- ----------
- Syntax:
-   clear(table, [a])
- Parameters:
-   table - name of table
-   a - a dictionary of values
- Returns:
-   A dictionary with an empty row
- Description:
-   This method clears all the attributes to values determined by the types.
-   Numeric types are set to 0, dates are set to 'TODAY' and everything
-   else is set to the empty string.  If the array argument is present,
-   it is used as the array and any entries matching attribute names
-   are cleared with everything else left unchanged.
-
- 3.8. delete
- -----------
- Syntax:
-   delete(table, a)
- Parameters:
-   table - name of table
-   a - a dictionary of values
- Returns:
-   None
- Description:
-   This method deletes the row from a table.  It deletes based on the OID
-   as munged as described above.
-
-
-4. DB-API reference
-===================
-
-  This section needs to be written.
-
-
-5. Todo
-=======
-
-The large object and direct access functions need much more attention.
-
-An update query should return the number of rows affected.
-
-The C module needs to be cleaned up and redundant code merged.
-
-The DB-API module needs to be documented.
-
-The fetch method should use real cursors.
-
-
-6. Future directions
-====================
-
-Users should be able to register their own types with _pg.
-
-I would like a new method that returns a dictionary of dictionaries from
-a SELECT.

-Thanks to thilo@eevolute.com and others for this README and the RPM
-
-Note: The precompiled RPM package is not available at www.eevolute.com.
-  You may use the spec file provided with PyGreSQL to build your

-INSTALLING PyGreSQL on Redhat Linux 5.1 or 5.2
-==============================================
-
-Things are pretty easy on Redhat Linux.  You can either get a precompiled
-RPM package from
-
-        ftp://www.eevolute.com/pub/python/
-
-or try in compile and install it yourself:
-
-bash$ make redhat       # this just compiles the module as a shared object
-cc -fpic -shared -o _pg.so -I/usr/include/python1.5 pgmodule.c -lpq
-bash$ python            # you can test it from your local directory
-Python 1.5.1 (#1, May  6 1998, 01:48:27)  [GCC 2.7.2.3] on linux-i386
-Copyright 1991-1995 Stichting Mathematisch Centrum, Amsterdam
->>> import _pg
->>> db = _pg.connect('thilo', 'localhost')
->>> db.query("INSERT INTO test VALUES ('ping', 'pong')")
-18304
->>> db.query("SELECT * FROM test")
-eins|zwei
-----+----
-ping|pong
-(1 row)
-
-bash$ su                # Yow! Seems to work - now install it properly
-bash# cp _pg.so /usr/lib/python1.5/lib-dynload 
-
-done!
-
-Oliver White (ojw@muzak.iinet.net.au) sent me the following information
-about installing on Debian.
-
-Hi, I thought you might want to upgrade your documentation for PyGreSQL
-to let people know they can get it by simply typing 'apt-get install
-python-pygresql', on debian (duh). This would have saved me a lot of
-trouble.

-""" pgdb - DB-SIG compliant module for PygreSQL.
-
-	(c) 1999, Pascal Andre <andre@via.ecp.fr>.
-	See package documentation for further information on copyright.
-
-	Inline documentation is sparse.  See DB-SIG 2.0 specification for
-	usage information.
-
-		basic usage:
-
-		pgdb.connect(connect_string) -> connection
-			connect_string = 'host:database:user:password:opt:tty'
-			All parts are optional. You may also pass host through
-			password as keyword arguments. To pass a port, pass it in
-			the host keyword parameter:
-				pgdb.connect(host='localhost:5432')
-
-		connection.cursor() -> cursor
-
-		connection.commit()
-
-		connection.close()
-
-		connection.rollback()
-
-		cursor.execute(query[, params])
-			execute a query, binding params (a dictionary) if it is
-			passed. The binding syntax is the same as the % operator
-			for dictionaries, and no quoting is done.
-
-		cursor.executemany(query, list of params)
-			execute a query many times, binding each param dictionary
-			from the list.
-
-		cursor.fetchone() -> [value, value, ...]
-
-		cursor.fetchall() -> [[value, value, ...], ...]
-
-		cursor.fetchmany([size]) -> [[value, value, ...], ...]
-			returns size or cursor.arraysize number of rows from result
-			set. Default cursor.arraysize is 1.
-
-		cursor.description -> [(column_name, type_name, display_size,
-			internal_size, precision, scale, null_ok), ...]
-
-			Note that precision, scale and null_ok are not implemented.
-
-		cursor.rowcount
-			number of rows available in the result set. Available after
-			a call to execute.
-
-		cursor.close()
