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/include/access/gist.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/include/access/gist.h') diff --git a/src/include/access/gist.h b/src/include/access/gist.h index af9b7c3b0dc..760c025af6d 100644 --- a/src/include/access/gist.h +++ b/src/include/access/gist.h @@ -7,7 +7,7 @@ * Portions Copyright (c) 1996-2001, PostgreSQL Global Development Group * Portions Copyright (c) 1994, Regents of the University of California * - * $Id: gist.h,v 1.30 2001/08/10 14:34:28 momjian Exp $ + * $Id: gist.h,v 1.31 2001/08/21 16:36:05 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -73,8 +73,8 @@ typedef struct GISTSTATE FmgrInfo picksplitFn[INDEX_MAX_KEYS]; FmgrInfo equalFn[INDEX_MAX_KEYS]; bool attbyval[INDEX_MAX_KEYS]; - bool haskeytype; - bool keytypbyval; + bool haskeytype[INDEX_MAX_KEYS]; + bool keytypbyval[INDEX_MAX_KEYS]; } GISTSTATE; -- cgit v1.2.3
