Bruce Momjian	a67387b6b4	Please apply attached patch to contrib/intarray (7.2, 7.3). ... Fixed bug with '=' operator for gist__int_ops and define '=' operator for gist__intbig_ops opclass. Now '=' operator is consistent with standard 'array' type. Thanks Achilleus Mantzios for bug report and suggestion. Oleg Bartunov	24 years ago
Tom Lane	56f5dc9078	Remove bogus pg_amop insertion commands, per discussion of 25-Oct. ... No change in results of script, but perhaps less confusion for people reading it.	24 years ago
Tom Lane	14b0da2ac3	Changes: ... 1. gist__int_ops is now without lossy 2. added sort entry in picksplit Oleg Bartunov	25 years ago
Bruce Momjian	484a0fa454	please apply attached patch to current CVS. ... Changes: 1. Added support for boolean queries (indexable operator @@, looks like a @@ '1|(2&3)' 2. Some code cleanup and optimization Regards, Oleg	25 years ago
Tom Lane	a54075a6d6	Update GiST for new pg_opclass arrangement (finally a clean solution ... for haskeytype). Update GiST contrib modules too. Add linear-time split algorithm for R-tree GiST opclass. From Oleg Bartunov and Teodor Sigaev.	25 years ago
Tom Lane	f933766ba7	Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions in ... pgsql-hackers. pg_opclass now has a row for each opclass supported by each index AM, not a row for each opclass name. This allows pg_opclass to show directly whether an AM supports an opclass, and furthermore makes it possible to store additional information about an opclass that might be AM-dependent. pg_opclass and pg_amop now store "lossy" and "haskeytype" information that we previously expected the user to remember to provide in CREATE INDEX commands. Lossiness is no longer an index-level property, but is associated with the use of a particular operator in a particular index opclass. Along the way, IndexSupportInitialize now uses the syscaches to retrieve pg_amop and pg_amproc entries. I find this reduces backend launch time by about ten percent, at the cost of a couple more special cases in catcache.c's IndexScanOK. Initial work by Oleg Bartunov and Teodor Sigaev, further hacking by Tom Lane. initdb forced.	25 years ago
Tom Lane	bf56f0759b	Make OIDs optional, per discussions in pghackers. WITH OIDS is still the ... default, but OIDS are removed from many system catalogs that don't need them. Some interesting side effects: TOAST pointers are 20 bytes not 32 now; pg_description has a three-column key instead of one. Bugs fixed in passing: BINARY cursors work again; pg_class.relhaspkey has some usefulness; pg_dump dumps comments on indexes, rules, and triggers in a valid order. initdb forced.	25 years ago
Bruce Momjian	13923be7c8	1. null-safe interface to GiST ... (as proposed in http://fts.postgresql.org/db/mw/msg.html?mid=1028327) 2. support for 'pass-by-value' arguments - to test this we used special opclass for int4 with values in range [0-2^15] More testing will be done after resolving problem with index_formtuple and implementation of B-tree using GiST 3. small patch to contrib modules (seg,cube,rtree_gist,intarray) - mark functions as 'isstrict' where needed.
