Also performed an initial run through of upgrading our Copyright date to extend to 2005 ... first run here was very simple ... change everything where: grep 1996-2004 && the word 'Copyright' ... scanned through the generated list with 'less' first, and after, to make sure that I only picked up the right entries ...

2004-05-26Reimplement the linked list data structure used throughout the backend.Neil Conway
In the past, we used a 'Lispy' linked list implementation: a "list" was merely a pointer to the head node of the list. The problem with that design is that it makes lappend() and length() linear time. This patch fixes that problem (and others) by maintaining a count of the list length and a pointer to the tail node along with each head node pointer. A "list" is now a pointer to a structure containing some meta-data about the list; the head and tail pointers in that structure refer to ListCell structures that maintain the actual linked list of nodes. The function names of the list API have also been changed to, I hope, be more logically consistent. By default, the old function names are still available; they will be disabled-by-default once the rest of the tree has been updated to use the new API names.
2004-05-14Tighten parsing of boolean options to CREATE TYPE and related functions,Tom Lane
so as to deliver more useful error messages for mistakes like 'PASSEDBYVALUE = f'. Per gripe from Gaetano Mendola.
2004-05-07Solve the 'Turkish problem' with undesirable locale behavior for caseTom Lane
conversion of basic ASCII letters. Remove all uses of strcasecmp and strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp; remove most but not all direct uses of toupper and tolower in favor of pg_toupper and pg_tolower. These functions use the same notions of case folding already developed for identifier case conversion. I left the straight locale-based folding in place for situations where we are just manipulating user data and not trying to match it to built-in strings --- for example, the SQL upper() function is still locale dependent. Perhaps this will prove not to be what's wanted, but at the moment we can initdb and pass regression tests in Turkish locale.
2004-02-21Implement a solution to the 'Turkish locale downcases I incorrectly'Tom Lane
problem, per previous discussion. Make some additional changes to centralize the knowledge of just how identifier downcasing is done, in hopes of simplifying any future tweaking in this area.

2003-07-20Another round of error message editing, covering backend/commands/.Tom Lane
2002-09-21Provide an upgrade strategy for dump files containing functions declaredTom Lane
with OPAQUE. CREATE LANGUAGE, CREATE TRIGGER, and CREATE TYPE will all accept references to functions declared with OPAQUE --- but they will issue a NOTICE, and will modify the function entries in pg_proc to have the preferred type-safe argument or result types instead of OPAQUE. Per recent pghackers discussions.

2002-08-10Allow schema-qualified operator names to be used in the optionalTom Lane
arguments of CREATE OPERATOR.
2002-06-20Update copyright to 2002.Bruce Momjian
2002-05-22Modify sequence state storage to eliminate dangling-pointer problemTom Lane
exemplified by bug #671. Moving the storage to relcache turned out to be a bad idea because relcache might decide to discard the info. Instead, open and close the relcache entry on each sequence operation, and use a record of the current XID to discover whether we already hold AccessShareLock on the sequence.
2002-04-15The contents of command.c, creatinh.c, define.c, remove.c and rename.cTom Lane
have been divided according to the type of object manipulated - so ALTER TABLE code is in tablecmds.c, aggregate commands in aggregatecmds.c and so on. A few common support routines remain in define.c (prototypes in src/include/commands/defrem.h). No code has been changed except for includes to reflect the new files. The prototypes for aggregatecmds.c, functioncmds.c, operatorcmds.c, and typecmds.c remain in src/include/commands/defrem.h. From John Gray <jgray@azuli.co.uk>
2002-04-11Restructure representation of aggregate functions so that they have pg_procTom Lane
entries, per pghackers discussion. This fixes aggregates to live in namespaces, and also simplifies/speeds up lookup in parse_func.c. Also, add a 'proimplicit' flag to pg_proc that controls whether a type coercion function may be invoked implicitly, or only explicitly. The current settings of these flags are more permissive than I would like, but we will need to debate and refine the behavior; for now, I avoided breaking regression tests as much as I could.
2002-04-09Functions live in namespaces. Qualified function names work, egTom Lane
SELECT schema1.func2(...). Aggregate names can be qualified at the syntactic level, but the qualification is ignored for the moment.
2002-04-05Divide functions into three volatility classes (immutable, stable, andTom Lane
volatile), rather than the old cachable/noncachable distinction. This allows indexscan optimizations in many places where we formerly didn't. Also, add a pronamespace column to pg_proc (it doesn't do anything yet, however).
2002-03-29pg_type has a typnamespace column; system now supports creating typesTom Lane
in different namespaces. Also, cleanup work on relation namespace support: drop, alter, rename commands work for tables in non-default namespaces.
2002-03-20Code review for DOMAIN patch.Tom Lane
2002-03-19Add DOMAIN support. Includes manual pages and regression tests, fromBruce Momjian
Rod Taylor.
2002-03-07Back out domain patch until it works properly.Bruce Momjian
2002-03-06Ok. Updated patch attached.Bruce Momjian
- domain.patch -> source patch against pgsql in cvs - drop_domain.sgml and create_domain.sgml -> New doc/src/sgml/ref docs - dominfo.txt -> basic domain related queries I used for testing [ ADDED TO /doc] Enables domains of array elements -> CREATE DOMAIN dom int4[3][2]; Uses a typbasetype column to describe the origin of the domain. Copies data to attnotnull rather than processing in execMain(). Some documentation differences from earlier. If this is approved, I'll start working on pg_dump, and a \dD <domain> option in psql, and regression tests. I don't really feel like doing those until the system table structure settles for pg_type. CHECKS when added, will also be copied to to the table attributes. FK Constraints (if I ever figure out how) will be done similarly. Both will lbe handled by MergeDomainAttributes() which is called shortly before MergeAttributes(). Rod Taylor
2002-03-06Change made to elog:Bruce Momjian
o Change all current CVS messages of NOTICE to WARNING. We were going to do this just before 7.3 beta but it has to be done now, as you will see below. o Change current INFO messages that should be controlled by client_min_messages to NOTICE. o Force remaining INFO messages, like from EXPLAIN, VACUUM VERBOSE, etc. to always go to the client. o Remove INFO from the client_min_messages options and add NOTICE. Seems we do need three non-ERROR elog levels to handle the various behaviors we need for these messages. Regression passed.
2002-03-02Commit to match discussed elog() changes. Only update is that LOG isBruce Momjian
now just below FATAL in server_min_messages. Added more text to highlight ordering difference between it and client_min_messages. --------------------------------------------------------------------------- REALLYFATAL => PANIC STOP => PANIC New INFO level the prints to client by default New LOG level the prints to server log by default Cause VACUUM information to print only to the client NOTICE => INFO where purely information messages are sent DEBUG => LOG for purely server status messages DEBUG removed, kept as backward compatible DEBUG5, DEBUG4, DEBUG3, DEBUG2, DEBUG1 added DebugLvl removed in favor of new DEBUG[1-5] symbols New server_min_messages GUC parameter with values: DEBUG[5-1], INFO, NOTICE, ERROR, LOG, FATAL, PANIC New client_min_messages GUC parameter with values: DEBUG[5-1], LOG, INFO, NOTICE, ERROR, FATAL, PANIC Server startup now logged with LOG instead of DEBUG Remove debug_level GUC parameter elog() numbers now start at 10 Add test to print error message if older elog() values are passed to elog() Bootstrap mode now has a -d that requires an argument, like postmaster

2001-10-13Mention createlang when language not installed, per problem report.Bruce Momjian
2001-10-02Add CREATE OR REPLACE FUNCTION syntax to allow replacing a functionTom Lane
definition without changing the function's OID, thereby not breaking rules, views, triggers, etc that depend on it. From Gavin Sherry.
2001-09-08Clean up some confusion about where and how to set whereToSendOutput.Tom Lane
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.
2001-09-06Fix handling of pg_type.typdefault per bug report from Dave Blasby.Tom Lane
If there's anyone out there who's actually using datatype-defined default values, this will be an incompatible change in behavior ... but the old behavior was so broken that I doubt anyone was using it.
2001-08-03For some reason, CREATE TYPE has only accepted alignment specificationsTom Lane
of 'int4' and 'double'. Add 'char' and 'int2' to allow user-defined types to access the full set of supported alignments.
2001-06-21Fix strangely formatted comment.Bruce Momjian
2001-06-13Allow a non-superuser database owner to vacuum all tables in hisTom Lane
database, including system catalogs (but not the shared catalogs, since they don't really belong to his database). This is per recent mailing list discussion. Clean up some other code that also checks for database ownerness by introducing a test function is_dbadmin().
2001-05-18Small code cleanups,formatting.Bruce Momjian
2001-03-22Remove dashes in comments that don't need them, rewrap with pgindent.Bruce Momjian
2001-03-22pgindent run. Make it all clean.Bruce Momjian
2001-02-12Rearrange order of operations in heap_create_with_catalog so that ifTom Lane
two transactions create the same table name concurrently, the one that fails will complain about unique index pg_class_relname_index, rather than about pg_type_typname_index which'll confuse most people. Free side benefit: pg_class.reltype is correctly linked to the pg_type entry now. It's been zero in all but the preloaded pg_class entries since who knows when.
2001-01-24Change Copyright from PostgreSQL, Inc to PostgreSQL Global Development Group.Bruce Momjian
2000-12-03Ensure that all uses of <ctype.h> functions are applied to unsigned-charTom Lane
values, whether the local char type is signed or not. This is necessary for portability. Per discussion on pghackers around 9/16/00.
2000-11-20Revise handling of oldstyle/newstyle functions per recent discussionsTom Lane
in pghackers list. Support for oldstyle internal functions is gone (no longer needed, since conversion is complete) and pg_language entry 'internal' now implies newstyle call convention. pg_language entry 'newC' is gone; both old and newstyle dynamically loaded C functions are now called language 'C'. A newstyle function must be identified by an associated info routine. See src/backend/utils/fmgr/README.
2000-11-16Change SearchSysCache coding conventions so that a reference count isTom Lane
maintained for each cache entry. A cache entry will not be freed until the matching ReleaseSysCache call has been executed. This eliminates worries about cache entries getting dropped while still in use. See my posting to pg-hackers of even date for more info.
2000-10-07Arrange that no database accesses are attempted during parser() --- thisTom Lane
took some rejiggering of typename and ACL parsing, as well as moving parse_analyze call out of parser(). Restructure postgres.c processing so that parse analysis and rewrite are skipped when in abort-transaction state. Only COMMIT and ABORT statements will be processed beyond the raw parser() phase. This addresses problem of parser failing with database access errors while in aborted state (see pghackers discussions around 7/28/00). Also fix some bugs with COMMIT/ABORT statements appearing in the middle of a single query input string. Function, operator, and aggregate arguments/results can now use full TypeName production, in particular foo[] for array types. DROP OPERATOR and COMMENT ON OPERATOR were broken for unary operators. Allow CREATE AGGREGATE to accept unquoted numeric constants for initcond.
2000-07-22Arrays are toastable. (At least if you initdb, which I didn't force.)Tom Lane
Remove a bunch of crufty code for large-object-based arrays, which is superseded by TOAST and likely hasn't worked in a long time anyway. Clean up array code a little, and in particular eliminate its habit of scribbling on the input array (ie, modifying the input tuple :-().
2000-07-17Revise aggregate functions per earlier discussions in pghackers.Tom Lane
There's now only one transition value and transition function. NULL handling in aggregates is a lot cleaner. Also, use Numeric accumulators instead of integer accumulators for sum/avg on integer datatypes --- this avoids overflow at the cost of being a little slower. Implement VARIANCE() and STDDEV() aggregates in the standard backend. Also, enable new LIKE selectivity estimators by default. Unrelated change, but as long as I had to force initdb anyway...
2000-07-03TOASTJan Wieck
WARNING: This is actually broken - we have self-deadlocks due to concurrent changes in buffer management. Vadim and me are working on it. Jan
2000-05-28First round of changes for new fmgr interface. fmgr itself and theTom Lane
key call sites are changed, but most called functions are still oldstyle. An exception is that the PL managers are updated (so, for example, NULL handling now behaves as expected in plperl and plpgsql functions). NOTE initdb is forced due to added column in pg_proc.
