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. --- src/backend/commands/cluster.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/backend/commands/cluster.c') diff --git a/src/backend/commands/cluster.c b/src/backend/commands/cluster.c index 0d76c6e8d37..7d5d3e6cbdb 100644 --- a/src/backend/commands/cluster.c +++ b/src/backend/commands/cluster.c @@ -15,7 +15,7 @@ * * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/commands/cluster.c,v 1.68 2001/08/10 18:57:34 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/commands/cluster.c,v 1.69 2001/08/21 16:36:01 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -225,7 +225,6 @@ copy_index(Oid OIDOldIndex, Oid OIDNewHeap, char *NewIndexName) indexInfo, Old_pg_index_relation_Form->relam, Old_pg_index_Form->indclass, - Old_pg_index_Form->indislossy, Old_pg_index_Form->indisprimary, allowSystemTableMods); -- cgit v1.2.3
