2002-08-22	Add a bunch of pseudo-types to replace the behavior formerly associated	Tom Lane
	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 ...
2002-07-30	Replace ad-hoc insertions into pg_opclass and friends with CREATE	Tom Lane
	OPERATOR CLASS commands. Further tweaking of documentation for same.
2002-04-17	Opclasses live in namespaces. I also took the opportunity to create	Tom Lane
	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.
2001-08-22	Update GiST for new pg_opclass arrangement (finally a clean solution	Tom Lane
	for haskeytype). Update GiST contrib modules too. Add linear-time split algorithm for R-tree GiST opclass. From Oleg Bartunov and Teodor Sigaev.
2001-08-21	Restructure pg_opclass, pg_amop, and pg_amproc per previous discussions in	Tom Lane
	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.
2001-08-10	1. null-safe interface to GiST	Bruce Momjian
	(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. Oleg Bartunov
2001-05-31	Support for emulating RTREE indexing in GiST. Contributed by	Tom Lane
	Oleg Bartunov and Teodor Sigaev.
