From 902a6a0a4bc62d619a5ccd1ef0ff7fb3a5d897f1 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 11 Apr 2002 20:00:18 +0000 Subject: Restructure representation of aggregate functions so that they have pg_proc entries, per pghackers discussion. This fixes aggregates to live in namespaces, and also simplifies/speeds up lookup in parse_func.c. Also, add a 'proimplicit' flag to pg_proc that controls whether a type coercion function may be invoked implicitly, or only explicitly. The current settings of these flags are more permissive than I would like, but we will need to debate and refine the behavior; for now, I avoided breaking regression tests as much as I could. --- src/include/parser/parse_coerce.h | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'src/include/parser/parse_coerce.h') diff --git a/src/include/parser/parse_coerce.h b/src/include/parser/parse_coerce.h index 1c503aed653..47ce9b61c16 100644 --- a/src/include/parser/parse_coerce.h +++ b/src/include/parser/parse_coerce.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: parse_coerce.h,v 1.41 2002/03/20 19:45:07 tgl Exp $ + * $Id: parse_coerce.h,v 1.42 2002/04/11 20:00:15 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -38,9 +38,10 @@ extern bool IsBinaryCompatible(Oid type1, Oid type2); extern bool IsPreferredType(CATEGORY category, Oid type); extern CATEGORY TypeCategory(Oid type); -extern bool can_coerce_type(int nargs, Oid *input_typeids, Oid *func_typeids); +extern bool can_coerce_type(int nargs, Oid *input_typeids, Oid *func_typeids, + bool isExplicit); extern Node *coerce_type(ParseState *pstate, Node *node, Oid inputTypeId, - Oid targetTypeId, int32 atttypmod); + Oid targetTypeId, int32 atttypmod, bool isExplicit); extern Node *coerce_type_typmod(ParseState *pstate, Node *node, Oid targetTypeId, int32 atttypmod); -- cgit v1.2.3
