Tom Lane	3a6e2ff08a	Fix things so that fopen's, not only open's, pass FILE_SHARE_DELETE and other special flags on Windows. May fix intermittent 'Permission denied' errors. Magnus Hagander	20 years ago
Tom Lane	f6d7ef08a7	Dept. of second thoughts: if query fails part way through, shut down the pager before reporting the error.	20 years ago
Tom Lane	c2f60711d2	Create a FETCH_COUNT parameter that causes psql to execute SELECT-like queries via a cursor, fetching a limited number of rows at a time and therefore not risking exhausting memory. A disadvantage of the scheme is that 'aligned' output mode will align each group of rows independently leading to odd-looking output, but all the other output formats work reasonably well. Chris Mair, with some additional hacking by moi.	20 years ago
Bruce Momjian	7c5ac5ce22	Separate prepared statement and bind parameters with comma. Fix printing of NULL bind parameters, use "NULL".	20 years ago
Bruce Momjian	5f6f70a04f	Add autovacuum item: > o Turn on by default	20 years ago
Teodor Sigaev	f7efd4ea66	Fix mistyping	20 years ago
Tom Lane	0434c46db0	Invent an assign-hook mechanism for psql variables similar to the one existing for backend GUC variables, and use this to eliminate repeated fetching/parsing of psql variables in psql's inner loops. In a trivial test with lots of 'select 1;' commands, psql's CPU time went down almost 10%, although of course the effect on total elapsed time was much less. Per discussion about how to ensure the upcoming FETCH_COUNT patch doesn't cost any performance when not being used.	20 years ago
Teodor Sigaev	b681bfdd59	Fix BUG #2594 : Gin Indexes cause server to crash when it builds on empty table	20 years ago
Teodor Sigaev	72a3582522	Add description of tsvector type layout	20 years ago
Teodor Sigaev	3a214ab0f1	Remove pos comparison in silly_cmp_tsvector(): it is not a semantically significant	20 years ago
Teodor Sigaev	9711782628	Fix incorrect length of lexemes in silly_cmp_tsvector()	20 years ago
Michael Meskes	cda6d0a8d3	Second try committing the path changes.	20 years ago
Michael Meskes	67135eb1ef	Removed debug option from pg_regress call. Changed file paths in expected files too.	20 years ago
Michael Meskes	b1710339ba	Fixed parser and library to allow empty database names. Streamlined connection name parsing. Added Joachim's patch to shorten paths before diffing.	20 years ago
Peter Eisentraut	ba9f9bf1b1	Revert change to turn autovacuum on by default.	20 years ago
Bruce Momjian	f443258d4f	Only call log_after_parse() if necessary.	20 years ago
Bruce Momjian	bc24d5b976	Now bind displays prepare as detail, and execute displays prepare and optionally bind. I re-added the "statement:" label so people will understand why the line is being printed (it is log_*statement behavior). Use single quotes for bind values, instead of double quotes, and double literal single quotes in bind values (and document that). I also made use of the DETAIL line to have much cleaner output.	20 years ago

Tom Lane	1832cefda1	Fix pgstat_report_waiting() to not dump core if called before pgstat_bestart() has been called; else any lock-block occurring during InitPostgres() is disastrous. I believe this explains recent wasp regression failure; at least it explains the crash I got while trying to duplicate the problem. I also made pgstat_report_activity() safe against the same scenario, just in case. The report_waiting hazard was created by my patch of 19-Aug to include waiting status in pg_stat_activity.	20 years ago
Tom Lane	ae28cfe673	Partial fix for ecpg's VPATH problems. It compiles and successfully builds all the files needed for its regression tests, but the tests themselves fail because of diffs in the #line directives output by ecpg itself. Not sure what to do about that.	20 years ago
Tom Lane	fcba3b82e2	Tweak trivial_subqueryscan() to consider a SubqueryScan's targetlist trivial if it contains either Vars referencing the corresponding subplan columns, or Consts equaling the corresponding subplan columns. This lets the planner eliminate the SubqueryScan in some cases generated by generate_setop_tlist().	20 years ago
Peter Eisentraut	88b8110443	Turn autovacuum on by default. (stats_row_level is also on by default.) Threshold and scale factor are cut in half for more aggressive behavior.	20 years ago
Tom Lane	ea2e263539	Add new return codes SPI_OK_INSERT_RETURNING etc to the SPI API. Fix all the standard PLs to be able to return tuples from FOO_RETURNING statements as well as utility statements that return tuples. Also, fix oversight that SPI_processed wasn't set for a utility statement returning tuples. Per recent discussion.	20 years ago
Tom Lane	7a2fe85b03	Add some notes about why it's not a bug that RI_FKey_check calls HeapTupleSatisfiesItself without doing LockBuffer first. This code is a bit fragile, but AFAICS it's not actually broken.	20 years ago
Tom Lane	e06fda0a8b	Add a function GetLockConflicts() to lock.c to report xacts holding locks that would conflict with a specified lock request, without actually trying to get that lock. Use this instead of the former ad hoc method of doing the first wait step in CREATE INDEX CONCURRENTLY. Fixes problem with undetected deadlock and in many cases will allow the index creation to proceed sooner than it otherwise could've. Per discussion with Greg Stark.	20 years ago
Tom Lane	ca1fd0ea5b	Move xact.c's partial support for Lists of TransactionIds into pg_list.h. Needed because lock.c is now going to use the same type of list.	20 years ago
Michael Meskes	99a5619e7b	- Enabled single-quoted connection targets. - Fixed a memory leak/segfault in unsuccessful connection. - Some changes to test files.	20 years ago
Tom Lane	162e8f1fd5	Make saveHistory work properly on OS X when HISTFILE is set to /dev/null. Per discussion with Martin Atukunda.	20 years ago

Tom Lane	e093dcdd28	Add the ability to create indexes 'concurrently', that is, without blocking concurrent writes to the table. Greg Stark, with a little help from Tom Lane.	20 years ago

Michael Meskes	b7d5a88dbb	Need more defines in ecpg_config.h, patch sent by Rocco Altier <RoccoA@Routescape.com>	20 years ago
Tom Lane	f836c2e37e	Add some debug logging code to AllocateFile's failure path to log the specific Windows error code (GetLastError). This is a hopefully temporary hack to try to diagnose rare failures. Magnus Hagander	20 years ago
Bruce Momjian	6935652c34	Update XML2 documentation for xpath_table(). John Gray	20 years ago
Tom Lane	08ae5edc5c	Optimize the case where a btree indexscan has current and mark positions on the same index page; we can avoid data copying as well as buffer refcount manipulations in this common case. Makes for a small but noticeable improvement in mergejoin speed. Heikki Linnakangas	20 years ago

Michael Meskes	a6558b068d	Somehow my version compiled but the change didn't make it to CVS.	20 years ago
