From f933766ba7c5446a28d714904ae0c46d8b21b86a Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 21 Aug 2001 16:36:06 +0000 Subject: 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. --- contrib/rtree_gist/sql/rtree_gist.sql | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'contrib/rtree_gist/sql') diff --git a/contrib/rtree_gist/sql/rtree_gist.sql b/contrib/rtree_gist/sql/rtree_gist.sql index a0506213227..592d4c3e78b 100644 --- a/contrib/rtree_gist/sql/rtree_gist.sql +++ b/contrib/rtree_gist/sql/rtree_gist.sql @@ -32,7 +32,7 @@ select count(*) from polytmp where p && '(1000,1000),(0,0)'::polygon; drop index pix; -create index pix on polytmp using gist (p gist_poly_ops) with(islossy); +create index pix on polytmp using gist (p gist_poly_ops); select count(*) from polytmp where p && '(1000,1000),(0,0)'::polygon; -- cgit v1.2.3
