2004-02-27Adjust remove_redundant_join_clauses() so that when it has a choiceTom Lane
of which redundant clause to remove, it removes the more expensive one. In simple scenarios the clauses will be like 'var = var' and there's no difference, but we are now capable of considering cases where there are sub-selects in the clauses, and it makes a BIG difference.
2004-02-27genericcostestimate() neglected to include qual startup cost inTom Lane
indexTotalCost. I think this may not make any real difference in 7.4, but it definitely is a problem with CVS tip's new equation.
2004-02-27process_implied_equality must copy the substructure of the clauses itTom Lane
is generating, to avoid problems when subselects are involved. Per report from Damon Hart.
2004-02-27Fix a few omissions in the initcap() documentation & source codeNeil Conway
comments, make some unrelated improvements to the functions documentation, and perform some minor consistency cleanup elsewhere. Original initcap() change from Dennis B., additional changes by Neil C.
2004-02-26For immediate application to HEAD.Bruce Momjian
Corrects bit-rot of recently applied patch. win32/cygwin only. Claudio Natoli
2004-02-25For application to HEAD, following community review.Bruce Momjian
* Changes incorrect CYGWIN defines to __CYGWIN__ * Some localtime returns NULL checks (when unchecked cause SEGVs under Win32 regression tests) * Rationalized CreateSharedMemoryAndSemaphores and AttachSharedMemoryAndSemaphores (Bruce, I finally remembered to do it); requires attention. Claudio Natoli
2004-02-25Teach plpgsql's lexer about dollar-quoted literals.Tom Lane
Andrew Dunstan, some help from Tom Lane.
2004-02-24anyarray really needs to be declared with typalign = 'd', so that entriesTom Lane
in pg_statistic are correctly aligned if they contain values that require double alignment. Too bad we cannot force initdb for this in 7.4 branch.
2004-02-24Add %option nodefault to all our flex lexers. Fix a couple of rule gapsTom Lane
exposed thereby. AFAICT these would not lead to any worse problems than junk emitted on the backend's stdout, but we should have the option to catch possible worse errors in future.
2004-02-24Implement dollar-quoting in the backend lexer and psql. DocumentationTom Lane
is still lacking, as is support in plpgsql and other places, but this is the basic feature. Patch by Andrew Dunstan, some tweaking by Tom Lane. Also, enable %option nodefault in these two lexers, and patch some gaps revealed thereby.
2004-02-24- Corrected error handling in PGTYPEStimestamp_from_asc.Michael Meskes
- Set pgtypeslib version to 1.2.
2004-02-24Cause pg_dump to emit a 'SET client_encoding' command at the start ofTom Lane
any restore operation, thereby ensuring that dumped data is interpreted the same way it was dumped even if the target database has a different encoding. Per suggestions from Pavel Stehule and others. Also, simplify scheme for handling check_function_bodies ... we may as well just set that at the head of the script.
2004-02-24Don't crash when a rowtype argument to a plpgsql function is NULL.Tom Lane
Per report from Chris Campbell.
2004-02-23Fix obsolete comment.Tom Lane
2004-02-23Replace opendir/closedir calls throughout the backend with AllocateDirTom Lane
and FreeDir routines modeled on the existing AllocateFile/FreeFile. Like the latter, these routines will avoid failing on EMFILE/ENFILE conditions whenever possible, and will prevent leakage of directory descriptors if an elog() occurs while one is open. Also, reduce PANIC to ERROR in MoveOfflineLogs() --- this is not critical code and there is no reason to force a DB restart on failure. All per recent trouble report from Olivier Hubaut.
2004-02-23NOFILE isn't used anywhere any more.Tom Lane
2004-02-23Do a direct probe during postmaster startup to determine the maximumTom Lane
number of openable files and the number already opened. This eliminates depending on sysconf(_SC_OPEN_MAX), and allows much saner behavior on platforms where open-file slots are used up by semaphores.
2004-02-23Fixed incorrect output of indicator structs using the name of the data struct.Michael Meskes
2004-02-23Write #include <dl.h>, not #include "dl.h", to correctly reflect theTom Lane
fact that dl.h is a system header and not one of ours.
2004-02-22Move responsibility for copying argv[] array into ps_status.c, where itTom Lane
logically belongs. Arrange to update the _NSGetArgv() copy of the argv pointer on Darwin. (It seems likely that other NeXT-derived platforms also have an _NSGetArgv() problem, but until we have some reports I'll just make this #ifdef __darwin__.)
2004-02-21Fix random build breakage from log_disconnections patch.Tom Lane
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.
2004-02-19Re-implement psql's input scanning to use a flex-generated lexer, as perTom Lane
recent discussion. The lexer is used for both SQL command text and backslash commands. The purpose of this change is to make it easier to track the behavior of the backend's SQL lexer --- essentially identical flex rules are now used by psql. Also, this cleans up a lot of very squirrelly code in mainloop.c and command.c. The flex code is somewhat bulkier than the removed code, but should be lots easier to maintain.
2004-02-19Cosmetic changes (mostly whitespace) to make it easier to diff theTom Lane
backend lexer against psql's.
2004-02-18Here is a patch that implements setitimer() on win32. With this patchBruce Momjian
applied, deadlock detection and statement_timeout now works. The file timer.c goes into src/backend/port/win32/. The patch also removes two lines of "printf debugging" accidentally left in pqsignal.h, in the console control handler. Magnus Hagander
2004-02-18Added missing rule for DOUBLE variables.Michael Meskes
2004-02-18Improve the consistency of the error message emitted when rejectingNeil Conway
invalid input to the oid type. Also, remove some long-unused code from adt/numutils.c
2004-02-17Rename function log_session_end to log_disconnections.Bruce Momjian
2004-02-17Fix prototype for on_proc_exit in log_disconnections patch.Bruce Momjian
2004-02-17This patch brings up to date what I did last year (now unfortunatelyBruce Momjian
bitrotted) to allow the logging of the end of a session, enabled by the config setting "log_disconnections". Andrew Dunstan
2004-02-17Here is an updated version of the win32 readdir patch.Bruce Momjian
1) Now puts in exactly the same change as the current-cvs mingw code does. (see http://cvs.sourceforge.net/viewcvs.py/mingw/runtime/mingwex/dirent.c?r1= 1.3&r2=1.4, second part of the patch). 2) Updates both xlog.c and slru.c in backend/access/transam/ 3) Also updates pg_resetxlog, which also uses readdir() and checks the errno value after the loop. Magnus Hagander
2004-02-17Under Win32, stat() returns an st_ino field, but it has no meaning (onBruce Momjian
Win2K, and possibly all Win32 variants, it is always 0). This causes a number of problems in the dfmgr.c logic, which basically all revolve around the fact that *any* two files will appear to have the same inode. Claudio Natoli
2004-02-17Make use of statistics on index expressions. There are still someTom Lane
corner cases that could stand improvement, but it does all the basic stuff. A byproduct is that the selectivity routines are no longer constrained to working on simple Vars; we might in future be able to improve the behavior for subexpressions that don't match indexes.
2004-02-16Change may -> might, and remove an extra tab.Bruce Momjian
2004-02-16- Cleaned up parser a little bit. It does not make sense to allow aMichael Meskes
typename to be typedef'ed that cannot be parsed as variable type. - Allowed some SQL keywords to be used as C variable names.
2004-02-15First steps towards statistics on expressional (nee functional) indexes.Tom Lane
This commit teaches ANALYZE to store such stats in pg_statistic, but nothing is done yet about teaching the planner to use 'em. Also, repair longstanding oversight in separate ANALYZE command: it updated the pg_class.relpages and reltuples counts for the table proper, but not for indexes.
2004-02-15New translationPeter Eisentraut
2004-02-15- Allowed some C keywords to be used as SQL column names.Michael Meskes
2004-02-15 - Added missing braces to array parsing.Michael Meskes
- Set ecpg version to 3.1.1. - Removed that old debugging output that I forgot the last time.
2004-02-14Create crosstype comparison operators for date vs. timestamp and dateTom Lane
vs. timestamptz. This allows use of indexes for expressions like datecol >= date 'today' - interval '1 month' which were formerly not indexable without casting the righthand side down from timestamp to date.
2004-02-13Repair optimization bug I introduced in a moment of brain fade back inTom Lane
Nov 2002: when constant-expression simplification removes all the aggregate function calls from a query, that doesn't mean we can act as though there never were any aggregates. Per bug report from Gabor Szucs.
2004-02-13After further thought about support for gathering stats on functionalTom Lane
indexes, it seems like we ought to put another layer of indirection between the compute_stats functions and the actual data storage. This would allow us to compute the values on-the-fly, for example.
2004-02-13Try to make 'cross-database references are not implemented' errors aTom Lane
bit more helpful by identifying the specific qualified name being complained of.
2004-02-12Add hooks for type-specific calculation of ANALYZE statistics. Idea andTom Lane
coding by Mark Cave-Ayland, some kibitzing by Tom Lane. initdb forced due to new column in pg_type.
2004-02-12Add CVS ID tags to port/win32/files.Bruce Momjian
2004-02-12Avoid delaying postmaster shutdown by up to 10 seconds on platformsTom Lane
where signals do not terminate sleep() delays.
2004-02-12Improve \? wording, remove 'internal'.Bruce Momjian
2004-02-12Translation updatesPeter Eisentraut
2004-02-12Fixed bug where FlushRelationBuffers() did call StrategyInvalidateBuffer()Jan Wieck
for already empty buffers because their buffer tag was not cleard out when the buffers have been invalidated before. Also removed the misnamed BM_FREE bufhdr flag and replaced the checks, which effectively ask if the buffer is unpinned, with checks against the refcount field. Jan
