From 6cef5d2549110c6c0abb92215c2593e652024493 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 16 Apr 2002 23:08:12 +0000 Subject: Operators live in namespaces. CREATE/DROP/COMMENT ON OPERATOR take qualified operator names directly, for example CREATE OPERATOR myschema.+ ( ... ). To qualify an operator name in an expression you need to write OPERATOR(myschema.+) (thanks to Peter for suggesting an escape hatch). I also took advantage of having to reformat pg_operator to fix something that'd been bugging me for a while: mergejoinable operators should have explicit links to the associated cross-data-type comparison operators, rather than hardwiring an assumption that they are named < and >. --- src/backend/executor/nodeAgg.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src/backend/executor/nodeAgg.c') diff --git a/src/backend/executor/nodeAgg.c b/src/backend/executor/nodeAgg.c index 3ccbcd8efc8..6ded8c5604a 100644 --- a/src/backend/executor/nodeAgg.c +++ b/src/backend/executor/nodeAgg.c @@ -46,7 +46,7 @@ * Portions Copyright (c) 1994, Regents of the University of California * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/executor/nodeAgg.c,v 1.81 2002/04/11 19:59:58 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/executor/nodeAgg.c,v 1.82 2002/04/16 23:08:10 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -925,7 +925,8 @@ ExecInitAgg(Agg *node, EState *estate, Plan *parent) &peraggstate->inputtypeLen, &peraggstate->inputtypeByVal); - eq_function = compatible_oper_funcid("=", inputType, inputType, + eq_function = compatible_oper_funcid(makeList1(makeString("=")), + inputType, inputType, true); if (!OidIsValid(eq_function)) elog(ERROR, "Unable to identify an equality operator for type '%s'", -- cgit v1.2.3
