From 1fd0c59e25063e664f8a5cee6f723470c5979544 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 5 Dec 2002 15:50:39 +0000 Subject: Phase 1 of read-only-plans project: cause executor state nodes to point to plan nodes, not vice-versa. All executor state nodes now inherit from struct PlanState. Copying of plan trees has been simplified by not storing a list of SubPlans in Plan nodes (eliminating duplicate links). The executor still needs such a list, but it can build it during ExecutorStart since it has to scan the plan tree anyway. No initdb forced since no stored-on-disk structures changed, but you will need a full recompile because of node-numbering changes. --- src/include/tcop/pquery.h | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'src/include/tcop') diff --git a/src/include/tcop/pquery.h b/src/include/tcop/pquery.h index a29b1857ec..b001424997 100644 --- a/src/include/tcop/pquery.h +++ b/src/include/tcop/pquery.h @@ -7,7 +7,7 @@ * Portions Copyright (c) 1996-2002, PostgreSQL Global Development Group * Portions Copyright (c) 1994, Regents of the University of California * - * $Id: pquery.h,v 1.22 2002/09/04 20:31:45 momjian Exp $ + * $Id: pquery.h,v 1.23 2002/12/05 15:50:39 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -21,8 +21,6 @@ extern void ProcessQuery(Query *parsetree, Plan *plan, CommandDest dest, char *completionTag); -extern EState *CreateExecutorState(void); - extern Portal PreparePortal(char *portalName); #endif /* PQUERY_H */ -- cgit v1.2.1
