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/backend/parser/parse_expr.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'src/backend/parser/parse_expr.c') diff --git a/src/backend/parser/parse_expr.c b/src/backend/parser/parse_expr.c index f8449716061..916c1da4a68 100644 --- a/src/backend/parser/parse_expr.c +++ b/src/backend/parser/parse_expr.c @@ -8,7 +8,7 @@ * * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/parser/parse_expr.c,v 1.113 2002/04/09 20:35:52 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/parser/parse_expr.c,v 1.114 2002/04/11 20:00:00 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -1174,7 +1174,8 @@ parser_typecast_expression(ParseState *pstate, if (inputType != targetType) { expr = CoerceTargetExpr(pstate, expr, inputType, - targetType, typename->typmod); + targetType, typename->typmod, + true); /* explicit coercion */ if (expr == NULL) elog(ERROR, "Cannot cast type '%s' to '%s'", format_type_be(inputType), -- cgit v1.2.3
