fall back to `cd $srcdir && /bin/pwd` = `/bin/pwd`. One of these ought to
work, and if not, prep_buildtree is harmless.

driver's test suite. With previous patches applied, this reduces
the number of failures of the test suite from 6 to 4. The patch
fixes the test case itself, rather than the driver.
Details:
1) The driver correctly provided DatabaseMetaData about the sort
order of NULLs. This was confirmed by Peter Eisentraut on
pgsql-hackers. I fixed the test to accept/require the current
behaviour, and made it dependent on the backend version. See
nullsAreSortedAtStart(), nullsAreSortedAtEnd(),
nullsAreSortedHigh() and nullsAreSortedLow().
2) DatabaseMetaData.supportsOrderByUnrelated() correctly
returned true (an ORDER BY clause can contain columns that are
not in the SELECT clause), but the test case required false.
Fixed that.
3) Replaced deprecated assert() of junit.framework.TestCase by
assertEquals(), assertTrue() and assertNotNull(). This is
because assert will be a new keyword in Java 1.4.
4) Replaced assert(message,false) by the more elegant
fail(message).

This patch does the following:
- Adds binary datatype support (bytea)
- Changes getXXXStream()/setXXXStream() methods to be spec compliant
- Adds ability to revert to old behavior
Details:
Adds support for the binary type bytea. The ResultSet.getBytes() and
PreparedStatement.setBytes() methods now work against columns of bytea
type. This is a change in behavior from the previous code which assumed
the column type was OID and thus a LargeObject. The new behavior is
more complient with the JDBC spec as BLOB/CLOB are to be used for
LargeObjects and the getBytes()/setBytes() methods are for the databases
binary datatype (which is bytea in postgres).
Changes the behavior of the getBinaryStream(), getAsciiStream(),
getCharacterStream(), getUnicodeStream() and their setXXXStream()
counterparts. These methos now work against either the bytea type
(BinaryStream) or the text types (AsciiStream, CharacterStream,
UnicodeStream). The previous behavior was that these all assumed the
underlying column was of type OID and thus a LargeObject. The
spec/javadoc for these methods indicate that they are for LONGVARCHAR
and LONGVARBINARY datatypes, which are distinct from the BLOB/CLOB
datatypes. Given that the bytea and text types support upto 1G, they
are the LONGVARBINARY and LONGVARCHAR datatypes in postgres.
Added support for turning off the above new functionality. Given that
the changes above are not backwardly compatible (however they are more
spec complient), I added the ability to revert back to the old behavior.
The Connection now takes an optional parameter named 'compatible'. If
the value of '7.1' is passed, the driver reverts to the 7.1 behavior.
If the parameter is not passed or the value '7.2' is passed the behavior
is the new behavior. The mechanism put in place can be used in the
future when/if similar needs arise to change behavior. This is
patterned after how Oracle does this (i.e. Oracle has a 'compatible'
parameter that behaves in a similar manner).
Misc fixes. Cleaned up a few things I encountered along the way.
Note that in testing the patch I needed to ignore whitespace differences
in order to get it to apply cleanly (i.e. patch -l -i byteapatch.diff).
Also this patch introduces a new file
(src/interfaces/jdbc/org/postgresql/util/PGbytea.java).

>there is still an unpatched reference to pg_description in
>getColumns(), in both jdbc1 and jdbc2.
This was introduced by Jeroen's patch (see
http://fts.postgresql.org/db/mw/msg.html?mid=1032468). Attached
is a patch that returns getColumns() to using "select
obj_description()" instead of direct access to pg_description,
as per the request by Tom.
I've incorporated Jeroen's fix to left outer join with
pg_attrdef instead of inner join, so getColumns() also returns
columns without a default value.
I have, however, not included Jeroen's attempt to combine
multiple queries into one huge multi-join query for better
performance, because:
1) I don't know how to do that using obj_description() instead
of direct access to pg_description
2) I don't think a performance improvement (if any) in this
method is very important
Because of the outer join, getColumns() will only work with a
backend >= 7.1. Since the conditional coding for 7.1/7.2 and
jdbc1/jdbc2 is already giving me headaches I didn't pursue a
pre-7.1 solution.

ConnectionTest.testTransactionIsolation() in the JDBC driver's
test suite. This reduces the number of failures of the test
suite from 7 to 6. The patch fixes the test case itself, rather
than the driver.
In addition to the change described in my posting below, I fixed
the part of the test with autocommit enabled. The author of the
test assumed that setting the transaction isolation level would
have no effect, but in fact it does. Perhaps the test case
worked with pre-7.1 behaviour, when the JDBC driver set the
isolation level in every transaction, instead of using "set
session characteristics". Anyway, now it works with a backend
built from current CVS and the behaviour is JDBC compliant.
I also extended the test case by changing the isolation level
before beginning a transaction and verifying it inside the
transaction.

Given the following table:
test=# \d f
Table "f"
Column | Type | Modifiers
--------+---------+-----------
i | integer |
test | text |
If I do the following:
test=# insert into f values(1,'test');
INSERT 139549 1
test=# select i::int8,test from f;
?column? | test
----------+------
1 | test
(1 row)
It doesn't make much sense that the first column should be called
'?column?'.
The patch results in the output appearing like this:
test=# select i::int8,test from f;
i | test
---+------
1 | test
(1 row)

PostgreSQL to support unicode-conversion, but retains binary
compatibility among Tcl versions.
However, it neither checks at compile time not at runtime, if support
for unicode-conversion does really exist and it doesn't prevent the
user from changing the client encoding after initialization. I think
there should be warnings about this somewhere in the documentation.

Assign the fixed user id 1 to the user created by initdb.
A stand-alone backend will always set the user id to 1.
(Consequently, the name of that user is no longer important.)
In stand-alone mode, the user id 1 will have implicit superuser
status, to allow repairs even if there are no users defined.
Print a warning message when starting in stand-alone mode when no
users are defined.
Disallow dropping the current user and session user.
Granting/revoking superuser status also grants/revokes usecatupd.
(Previously, it would never grant it back. This could lead to "deadlocks".)
CREATE USER and CREATE GROUP will start allocating user ids at 100
(unless explicitly specified), to prevent accidental creation of a
superuser (plus some room for future extensions).

Forget it! A default client encoding must be set by actual database encoding...
Please apply the small attached patch that solve it better.

We will no longer try to send elog messages to the client before we have
initialized backend libpq (oops); however, reporting bogus commandline
switches via elog does work now (not irrelevant, because of PGOPTIONS).
Fix problem with inappropriate sending of checkpoint-process messages
to stderr.

suite. This reduces the number of failures from 9 to 7.
Both ConnectionTest and JBuilderTest did not create their own
tables, which caused these test cases to fail with "relation ...
does not exist". It appears these test cases relied on tables
created by the example code elsewhere in the source tree. I've
added the necessary "create table" and "drop table" statements
to the test cases, using the column definitions from the example
code.
While working on that I modified the helper method createTable
in JDBC2Tests.java to take a table parameter, rather than using
table names passed via the properties in build.xml. I'm not sure
what that was good for, and in fact, except for the default
table name "jdbctest", this functionality wasn't used at all.

discussion on pgsql-hackers (especially the frightening memory dump in
<12273.999562219@sss.pgh.pa.us>), we decided that it is best not to
use identifiers from an untrusted source at all. Therefore, all
claims of the suitability of PQescapeString() for identifiers have
been removed.
