From 1eef280d6186782b4adfbd6a9cb97413f7c46b8b Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Fri, 30 Jul 2010 17:57:25 +0000 Subject: Improved version of patch to protect pg_get_expr() against misuse: look through join alias Vars to avoid breaking join queries, and move the test to someplace where it will catch more possible ways of calling a function. We still ought to throw away the whole thing in favor of a data-type-based solution, but that's not feasible in the back branches. Completion of back-port of my patch of yesterday. --- src/include/parser/parse_func.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) (limited to 'src/include/parser/parse_func.h') diff --git a/src/include/parser/parse_func.h b/src/include/parser/parse_func.h index 5d203e60cae..f45e096e6db 100644 --- a/src/include/parser/parse_func.h +++ b/src/include/parser/parse_func.h @@ -7,7 +7,7 @@ * Portions Copyright (c) 1996-2005, PostgreSQL Global Development Group * Portions Copyright (c) 1994, Regents of the University of California * - * $PostgreSQL: pgsql/src/include/parser/parse_func.h,v 1.53 2004/12/31 22:03:38 pgsql Exp $ + * $PostgreSQL: pgsql/src/include/parser/parse_func.h,v 1.53.4.1 2010/07/30 17:57:25 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -78,4 +78,6 @@ extern Oid LookupFuncName(List *funcname, int nargs, const Oid *argtypes, extern Oid LookupFuncNameTypeNames(List *funcname, List *argtypes, bool noError); +extern void check_pg_get_expr_args(ParseState *pstate, Oid fnoid, List *args); + #endif /* PARSE_FUNC_H */ -- cgit v1.2.3
