From fa5c8a055a02e44f446e4593e397c33a572c4d67 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 12 Nov 2003 21:15:59 +0000 Subject: Cross-data-type comparisons are now indexable by btrees, pursuant to my pghackers proposal of 8-Nov. All the existing cross-type comparison operators (int2/int4/int8 and float4/float8) have appropriate support. The original proposal of storing the right-hand-side datatype as part of the primary key for pg_amop and pg_amproc got modified a bit in the event; it is easier to store zero as the 'default' case and only store a nonzero when the operator is actually cross-type. Along the way, remove the long-since-defunct bigbox_ops operator class. --- src/backend/access/gist/gistscan.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src/backend/access/gist/gistscan.c') diff --git a/src/backend/access/gist/gistscan.c b/src/backend/access/gist/gistscan.c index 960d1c2f25b..9b9d1f60341 100644 --- a/src/backend/access/gist/gistscan.c +++ b/src/backend/access/gist/gistscan.c @@ -8,7 +8,7 @@ * Portions Copyright (c) 1994, Regents of the University of California * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/access/gist/gistscan.c,v 1.48 2003/11/09 21:30:35 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/access/gist/gistscan.c,v 1.49 2003/11/12 21:15:46 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -109,7 +109,8 @@ gistrescan(PG_FUNCTION_ARGS) * Modify the scan key so that the Consistent function is called * for all comparisons.
