Peter Eisentraut	6a68f42648	The heralded `Grand Unified Configuration scheme' (GUC) ... That means you can now set your options in either or all of $PGDATA/configuration, some postmaster option (--enable-fsync=off), or set a SET command. The list of options is in backend/utils/misc/guc.c, documentation will be written post haste. pg_options is gone, so is that pq_geqo config file. Also removed were backend -K, -Q, and -T options (no longer applicable, although -d0 does the same as -Q). Added to configure an --enable-syslog option. changed all callers from TPRINTF to elog(DEBUG)	26 years ago
Tom Lane	25442d8d2f	Correct oversight in hashjoin cost estimation: nodeHash sizes its hash ... table for an average of NTUP_PER_BUCKET tuples/bucket, but cost_hashjoin was assuming a target load of one tuple/bucket. This was causing a noticeable underestimate of hashjoin costs.	26 years ago
Bruce Momjian	5c25d60244	Add: ... * Portions Copyright (c) 1996-2000, PostgreSQL, Inc to all files copyright Regents of Berkeley. Man, that's a lot of files.	26 years ago
Tom Lane	6d1efd76fb	Fix handling of NULL constraint conditions: per SQL92 spec, a NULL result ... from a constraint condition does not violate the constraint (cf. discussion on pghackers 12/9/99). Implemented by adding a parameter to ExecQual, specifying whether to return TRUE or FALSE when the qual result is really NULL in three-valued boolean logic. Currently, ExecRelCheck is the only caller that asks for TRUE, but if we find any other places that have the wrong response to NULL, it'll be easy to fix them.	26 years ago
Tom Lane	166b5c1def	Another round of planner/optimizer work. This is just restructuring and ... code cleanup; no major improvements yet. However, EXPLAIN does produce more intuitive outputs for nested loops with indexscans now...	26 years ago
Jan Wieck	397e9b32a3	Some changes to prepare for LONG attributes. ... Jan	26 years ago
Bruce Momjian	97dec77fab	Rename several destroy* functions/tags to drop*.	26 years ago
Tom Lane	db3c4c3a2d	Split 'BufFile' routines out of fd.c into a new module, buffile.c. Extend ... BufFile so that it handles multi-segment temporary files transparently. This allows sorts and hashes to work with data exceeding 2Gig (or whatever the local limit on file size is). Change psort.c to use relative seeks instead of absolute seeks for backwards scanning, so that it won't fail when the data volume exceeds 2Gig.	27 years ago
Bruce Momjian	3406901a29	Move some system includes into c.h, and remove duplicates.	27 years ago
Bruce Momjian	2e6b1e63a3	Remove unused #includes in *.c files.	27 years ago
Bruce Momjian	07842084fe	pgindent run over code.	27 years ago
Tom Lane	26069a58e8	Rewrite hash join to use simple linked lists instead of a ... fixed-size hashtable. This should prevent 'hashtable out of memory' errors, unless you really do run out of memory. Note: target size for hashtable is now taken from -S postmaster switch, not -B, since it is local memory in the backend rather than shared memory.	27 years ago
Tom Lane	71d5d95376	Update hash and join routines to use fd.c's new temp-file ... code, instead of not-very-bulletproof stuff they had before.	27 years ago
Tom Lane	9f82f9e459	Fix some nasty coredump bugs in hashjoin. This code was just ... about certain to fail anytime it decided the relation to be hashed was too big to fit in memory --- the code for 'batching' a series of hashjoins had multiple errors. I've fixed the easier problems. A remaining big problem is that you can get 'hashtable out of memory' if the code's guesstimate about how much overflow space it will need turns out wrong. That will require much more extensive revisions to fix, so I'm committing these fixes now before I start on that problem.	27 years ago
Tom Lane	af87148065	Fix some more hashjoin-related bugs in pg_operator. Fix ... hashjoin's hashFunc() so that it does the right thing with pass-by-value data types (the old code would always return 0 for int2 or char values, which would work but would slow things down a lot). Extend opr_sanity regress test to catch more kinds of errors.	27 years ago

Marc G. Fournier	374bb5d261	Some *very* major changes by darrenk@insightdist.com (Darren King) ... ========================================== What follows is a set of diffs that cleans up the usage of BLCKSZ. As a side effect, the person compiling the code can change the value of BLCKSZ _at_their_own_risk_. By that, I mean that I've tried it here at 4096 and 16384 with no ill-effects. A value of 4096 _shouldn't_ affect much as far as the kernel/file system goes, but making it bigger than 8192 can have severe consequences if you don't know what you're doing. 16394 worked for me, _BUT_ when I went to 32768 and did an initdb, the SCSI driver broke and the partition that I was running under went to hell in a hand basket. Had to reboot and do a good bit of fsck'ing to fix things up. The patch can be safely applied though. Just leave BLCKSZ = 8192 and everything is as before. It basically only cleans up all of the references to BLCKSZ in the code. If this patch is applied, a comment in the config.h file though above the BLCKSZ define with warning about monkeying around with it would be a good idea. Darren darrenk@insightdist.com (Also cleans up some of the #includes in files referencing BLCKSZ.) ==========================================	28 years ago

Marc G. Fournier	f796387b60	|From: Dan McGuirk <mcguirk@indirect.com> ... | |This patch fixes a backend crash that happens sometimes when you try to |join on a field that contains NULL in some rows. Postgres tries to |compute a hash value of the field you're joining on, but when the field |is NULL, the pointer it thinks is pointing to the data is really just |pointing to random memory. This forces the hash value of NULL to be 0. | |It seems that nothing matches NULL on joins, even other NULL's (with or |without this patch). Is that what's supposed to happen? |	30 years ago
