Peter Eisentraut	17cc78ef01	To fix the perpetually broken makefiles in the contrib tree, I have ... written a generic framework of rules that the contrib makefiles can use instead of writing their own each time. You only need to set a few variables and off you go.	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
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.

Bruce Momjian	7aac048b59	Attached is a patch to deal with the ones that I missed the first time ... around. I tested this patch under Cygwin and Linux. Note that I only changed dblink's Makefile in the most minimal way to fix the link problem under Cygwin (i.e., use the link rule from Makefile.shlib instead). dblink's Makefile should probably be further patched to be consistent with the other PostgreSQL Makefiles.
