From 27dc7e240bfd230ee1315cc00577a6ed72aff94a Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 24 Mar 2011 20:30:14 -0400 Subject: Fix handling of collation in SQL-language functions. Ensure that parameter symbols receive collation from the function's resolved input collation, and fix inlining to behave properly. BTW, this commit lays about 90% of the infrastructure needed to support use of argument names in SQL functions. Parsing of parameters is now done via the parser-hook infrastructure ... we'd just need to supply a column-ref hook ... --- src/include/executor/functions.h | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'src/include/executor/functions.h') diff --git a/src/include/executor/functions.h b/src/include/executor/functions.h index e725b24be20..b926e99cbbd 100644 --- a/src/include/executor/functions.h +++ b/src/include/executor/functions.h @@ -17,9 +17,18 @@ #include "nodes/execnodes.h" #include "tcop/dest.h" +/* This struct is known only within executor/functions.c */ +typedef struct SQLFunctionParseInfo *SQLFunctionParseInfoPtr; extern Datum fmgr_sql(PG_FUNCTION_ARGS); +extern SQLFunctionParseInfoPtr prepare_sql_fn_parse_info(HeapTuple procedureTuple, + Node *call_expr, + Oid inputCollation); + +extern void sql_fn_parser_setup(struct ParseState *pstate, + SQLFunctionParseInfoPtr pinfo); + extern bool check_sql_fn_retval(Oid func_id, Oid rettype, List *queryTreeList, bool *modifyTargetList, -- cgit v1.2.3
