From d64713df7e5996ab3ab337b5e0901cf2c53773f9 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 12 Apr 2011 19:19:24 -0400 Subject: Pass collations to functions in FunctionCallInfoData, not FmgrInfo. Since collation is effectively an argument, not a property of the function, FmgrInfo is really the wrong place for it; and this becomes critical in cases where a cached FmgrInfo is used for varying purposes that might need different collation settings. Fix by passing it in FunctionCallInfoData instead. In particular this allows a clean fix for bug #5970 (record_cmp not working). This requires touching a bit more code than the original method, but nobody ever thought that collations would not be an invasive patch... --- src/backend/executor/nodeSubplan.c | 4 ---- 1 file changed, 4 deletions(-) (limited to 'src/backend/executor/nodeSubplan.c') diff --git a/src/backend/executor/nodeSubplan.c b/src/backend/executor/nodeSubplan.c index 08a3017e614..4fcb66bbb03 100644 --- a/src/backend/executor/nodeSubplan.c +++ b/src/backend/executor/nodeSubplan.c @@ -831,8 +831,6 @@ ExecInitSubPlan(SubPlan *subplan, PlanState *parent) /* Lookup the equality function (potentially cross-type) */ fmgr_info(opexpr->opfuncid, &sstate->cur_eq_funcs[i - 1]); - fmgr_info_set_collation(opexpr->inputcollid, - &sstate->cur_eq_funcs[i - 1]); fmgr_info_set_expr((Node *) opexpr, &sstate->cur_eq_funcs[i - 1]); /* Look up the equality function for the RHS type */ @@ -841,8 +839,6 @@ ExecInitSubPlan(SubPlan *subplan, PlanState *parent) elog(ERROR, "could not find compatible hash operator for operator %u", opexpr->opno); fmgr_info(get_opcode(rhs_eq_oper), &sstate->tab_eq_funcs[i - 1]); - fmgr_info_set_collation(opexpr->inputcollid, - &sstate->tab_eq_funcs[i - 1]); /* Lookup the associated hash functions */ if (!get_op_hash_functions(opexpr->opno, -- cgit v1.2.3
