Alvaro Herrera	7861d72ea2	Modify the float4 datatype to be pass-by-val. Along the way, remove the last ... uses of the long-deprecated float32 in contrib/seg; the definitions themselves are still there, but no longer used. fmgr/README updated to match. I added a CREATE FUNCTION to account for existing seg_center() code in seg.c too, and some tests for it and the neighbor functions. At the same time, remove checks for NULL which are not needed (because the functions are declared STRICT). I had to do some adjustments to contrib's btree_gist too. The choices for representation there are not ideal for changing the underlying types :-( Original patch by Zoltan Boszormenyi, with some adjustments by me.	18 years ago
Tom Lane	9b5c8d45f6	Push index operator lossiness determination down to GIST/GIN opclass ... "consistent" functions, and remove pg_amop.opreqcheck, as per recent discussion. The main immediate benefit of this is that we no longer need 8.3's ugly hack of requiring @@@ rather than @@ to test weight-using tsquery searches on GIN indexes. In future it should be possible to optimize some other queries better than is done now, by detecting at runtime whether the index match is exact or not. Tom Lane, after an idea of Heikki's, and with some help from Teodor.	18 years ago
Bruce Momjian	33e2e02493	Add CVS version labels to all install/uninstall scripts.	18 years ago
Bruce Momjian	926bbab448	Make /contrib install/uninstall script consistent: ... remove transactions use create or replace function make formatting consistent set search patch on first line Add documentation on modifying *.sql to set the search patch, and mention that major upgrades should still run the installation scripts. Some of these issues were spotted by Tom today.	18 years ago
Tom Lane	f8203f908e	Support functions for index opclasses should be immutable. ... Found by running opr_sanity on contrib modules.	19 years ago
Tom Lane	684ad6a92f	Rename contrib contains/contained-by operators to @> and <@, per discussion.	20 years ago
Peter Eisentraut	7f4f42fa10	Clean up CREATE FUNCTION syntax usage in contrib and elsewhere, in ... particular get rid of single quotes around language names and old WITH () construct.	20 years ago
Tom Lane	54c80a3434	Adjust contrib/seg &< and &> operators so that r-tree indexing logic ... works properly for 1-D comparisons. Fix some other errors such as bogus commutator specifications.	21 years ago
Teodor Sigaev	f2c064afcb	Cleanup vectors of GISTENTRY and eliminate problem with 64-bit strict-aligned ... boxes. Change interface to user-defined GiST support methods union and picksplit. Now instead of bytea struct it used special GistEntryVector structure.	22 years ago
Tom Lane	043be9ad96	Make contrib/seg work with flex 2.5.31. Fix it up to have a real ... btree operator class, too, since in PG 7.4 you can't GROUP without one.	23 years ago
Tom Lane	f85f43dfb5	Backend support for autocommit removed, per recent discussions. The ... only remnant of this failed experiment is that the server will take SET AUTOCOMMIT TO ON. Still TODO: provide some client-side autocommit logic in libpq.	23 years ago
Bruce Momjian	aa4c702eac	Update /contrib for "autocommit TO 'on'". ... Create objects in public schema. Make spacing/capitalization consistent. Remove transaction block use for object creation. Remove unneeded function GRANTs.	24 years ago
Tom Lane	b663f3443b	Add a bunch of pseudo-types to replace the behavior formerly associated ... with OPAQUE, as per recent pghackers discussion. I still want to do some more work on the 'cstring' pseudo-type, but I'm going to commit the bulk of the changes now before the tree starts shifting under me ...	24 years ago
Tom Lane	65b6868b13	Replace ad-hoc insertions into pg_opclass and friends with CREATE ... OPERATOR CLASS commands. Further tweaking of documentation for same.	24 years ago
Tom Lane	27a54ae282	Opclasses live in namespaces. I also took the opportunity to create ... an 'opclass owner' column in pg_opclass. Nothing is done with it at present, but since there are plans to invent a CREATE OPERATOR CLASS command soon, we'll probably want DROP OPERATOR CLASS too, which suggests that a notion of ownership would be a good idea.	24 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
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.
