From 9cbd0c155d1602aad879f510256b626c58942080 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 20 Feb 2007 17:32:18 +0000 Subject: Remove the Query structure from the executor's API. This allows us to stop storing mostly-redundant Query trees in prepared statements, portals, etc. To replace Query, a new node type called PlannedStmt is inserted by the planner at the top of a completed plan tree; this carries just the fields of Query that are still needed at runtime. The statement lists kept in portals etc. now consist of intermixed PlannedStmt and bare utility-statement nodes --- no Query. This incidentally allows us to remove some fields from Query and Plan nodes that shouldn't have been there in the first place. Still to do: simplify the execution-time range table; at the moment the range table passed to the executor still contains Query trees for subqueries. initdb forced due to change of stored rules. --- src/backend/executor/execUtils.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/backend/executor/execUtils.c') diff --git a/src/backend/executor/execUtils.c b/src/backend/executor/execUtils.c index 91efba011ca..d9957573883 100644 --- a/src/backend/executor/execUtils.c +++ b/src/backend/executor/execUtils.c @@ -8,7 +8,7 @@ * * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/executor/execUtils.c,v 1.144 2007/02/06 17:35:20 tgl Exp $ + * $PostgreSQL: pgsql/src/backend/executor/execUtils.c,v 1.145 2007/02/20 17:32:14 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -242,7 +242,7 @@ InternalCreateExecutorState(MemoryContext qcontext, bool is_subquery) estate->es_per_tuple_exprcontext = NULL; - estate->es_topPlan = NULL; + estate->es_plannedstmt = NULL; estate->es_evalPlanQual = NULL; estate->es_evTupleNull = NULL; estate->es_evTuple = NULL; -- cgit v1.2.3
