Bruce Momjian	30854a53fe	Properly implement "Response files" for bcc. Add URL's to describe the feature for Win32 and bcc.	21 years ago
Teodor Sigaev	10d3c07875	Prevent rank change in case of duplicate search terms	21 years ago
Tom Lane	4e8af8d273	Replace ARC cache management algorithm with the similar but slightly simpler 2Q algorithm, to avoid possible problems with the pending patent on ARC. Testing so far suggests that there is little if any performance loss from doing this. Note that this patch is going into the 8.0 branch only; a much more extensive revision is planned for HEAD.	21 years ago
Tom Lane	3f16b38a23	Release proclock immediately in RemoveFromWaitQueue() if it represents no held locks. This maintains the invariant that proclocks are present only for procs that are holding or awaiting a lock; when this is not true, LockRelease will fail. Per report from Stephen Clouse.	21 years ago
Tom Lane	bfc2942321	Adjust OR indexscan logic to not generate redundant condition-free OR indexscans involving partial indexes. These would always be dominated by a simple indexscan on such an index, so there's no point in considering them. Fixes overoptimism in a patch I applied last October.	21 years ago
Tom Lane	3da9fd8544	Revert the logic for expanding AND/OR conditions in pred_test() to what it was in 7.4, and add some comments explaining why it has to be this way. I broke it for OR'd index predicates in a fit of code cleanup last summer. Per example from Sergey Koshcheyev.	21 years ago
Bruce Momjian	ba6b067ce8	Tab indent all actions in bcc32.mak, and do it on win32.mak too for consistency. Backpatch only bcc32.mak to 8.0.X.	21 years ago

Bruce Momjian	538e960939	Mention that some psql environment variables come from libpq and note more variables can be found in the libpq manual section. Mention .pgpass in the psql manual page section dealing with connection parameters and point to the libpq section for more details. Backpatch to 8.0.X.	21 years ago
Tom Lane	9843862b50	Fix SPI cursor support to allow scanning the results of utility commands that return tuples (such as EXPLAIN). Per gripe from Michael Fuhr. Side effect: fix an old bug that unintentionally disabled backward scans for all SPI-created cursors.	21 years ago
Michael Meskes	95b40b7f77	Fixed more parsing bugs in other CREATE statements.	21 years ago
Bruce Momjian	7dfc700b96	Update pginstaller URL to http://www.postgresql.org/ftp/win32/. Backpatch to 8.0.X.	21 years ago
Neil Conway	789aafebd5	ALTER TABLE ADD COLUMN exhibits a significant memory leak when adding a column with a default expression. In that situation, we need to rewrite the heap relation. To evaluate the new default expression, we use ExecEvalExpr(); however, this can allocate memory in the current memory context, and ATRewriteTable() does not switch out of the active portal's heap memory context. The end result is a rather large memory leak (on the order of gigabytes for a reasonably sized table). This patch changes ATRewriteTable() to switch to the per-tuple memory context before beginning the per-tuple loop. It also removes an explicit heap_freetuple() in the loop, since that is no longer needed. In an unrelated change, I noticed the code was scanning through the attributes of the new tuple descriptor for each tuple of the old table. I changed this to use precomputation, which should slightly speed up the loop. Thanks to steve@deefs.net for reporting the leak.	21 years ago
Michael Meskes	ef006ded8e	Fixed bug in parsing of CREATE AS statement.	21 years ago
Tom Lane	ae50aa7ee8	If we're gonna check for array overrun, we really should do so before overrunning the array, not after.	21 years ago
Neil Conway	6c5c748d64	Prevent 4 more buffer overruns in the PL/PgSQL parser. This is just a minimally-invasive fix for stable branches; a cleaner fix will be committed to HEAD soon.	21 years ago
Neil Conway	5b327fb917	Better late than never: document that the GiST API changed in 8.0 in the "incompatibilities" section of the release notes.	21 years ago
Tom Lane	c31570ed43	Document array behavior for out-of-range subscripts.	21 years ago
Tom Lane	0aeb7d8008	Repair CLUSTER failure after ALTER TABLE SET WITHOUT OIDS. Turns out there are corner cases involving dropping toasted columns in which the previous coding would fail, too: the new version of the table might not have any TOAST table, but we'd still propagate possibly-wide values of dropped columns forward.	21 years ago
Tom Lane	a7bbb6cd53	Fix minor thinko in logic to set dump order when dumping from a pre-7.3 database: aggregates should be dumped in the same pass as operators, not in the same pass as functions.	21 years ago
Tom Lane	c8460d571e	Ensure that all details of the ARC algorithm are hidden within freelist.c. This refactoring does not change any algorithms or data structures, just remove visibility of the ARC datastructures from other source files.	21 years ago
Tom Lane	f76390d75a	Improve performance of fmgr.c calling routines for cases with more than two arguments. Per suggestions from A. Ogawa.	21 years ago
Tom Lane	388a42c515	Adjust constant-folding of CASE expressions so that the simple comparison form of CASE (eg, CASE 0 WHEN 1 THEN ...) can be constant-folded as it was in 7.4. Also, avoid constant-folding result expressions that are certainly unreachable --- the former coding was a bit cavalier about this and could generate unexpected results for all-constant CASE expressions. Add regression test cases. Per report from Vlad Marchenko.	21 years ago
Bruce Momjian	722c886ba1	Improve wording of to_char() change in 8.1: The 8.1 release will remove the <function>to_char()</> function for intervals.	21 years ago

Bruce Momjian	8e2216db6c	Backpatch FAQ to 8.0.X.	21 years ago
Neil Conway	a8daceaa15	Fix a bug induced by the list-rewrite that resulted in incrementing the command counter more than necessary. Per report from Michael Fuhr.	21 years ago
Tom Lane	914db10289	Adjust estimate_num_groups() to not clamp per-relation group count estimate to less than the number of values estimated for any one grouping Var, as suggested by Manfred. This is intuitively right, and what's more it puts the plan choices in the subselect regression test back the way they were before ...	21 years ago
Tom Lane	86206573ed	Adjust plpgsql to allow assignment to an element of an array that is initially NULL. For 8.0 we changed the main executor to have this behavior in an UPDATE of an array column, but plpgsql's equivalent case was overlooked. Per report from Sven Willenberger.	21 years ago
Bruce Momjian	925320fe3d	Backpatch FAQ changes to 8.0.X.	21 years ago
Tom Lane	b46fa4ba81	Sync inet formatting code with recent BIND releases. In particular, fix bug with inconsistent selection of default mask length for "class D" addresses. Per report from Steve Atkins.	21 years ago
