From b9527e984092e838790b543b014c0c2720ea4f11 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Tue, 13 Mar 2007 00:33:44 +0000 Subject: First phase of plan-invalidation project: create a plan cache management module and teach PREPARE and protocol-level prepared statements to use it. In service of this, rearrange utility-statement processing so that parse analysis does not assume table schemas can't change before execution for utility statements (necessary because we don't attempt to re-acquire locks for utility statements when reusing a stored plan). This requires some refactoring of the ProcessUtility API, but it ends up cleaner anyway, for instance we can get rid of the QueryContext global. Still to do: fix up SPI and related code to use the plan cache; I'm tempted to try to make SQL functions use it too. Also, there are at least some aspects of system state that we want to ensure remain the same during a replan as in the original processing; search_path certainly ought to behave that way for instance, and perhaps there are others. --- src/backend/bootstrap/bootparse.y | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/backend/bootstrap') diff --git a/src/backend/bootstrap/bootparse.y b/src/backend/bootstrap/bootparse.y index 64c8c8139d..ff2f7f70c3 100644 --- a/src/backend/bootstrap/bootparse.y +++ b/src/backend/bootstrap/bootparse.y @@ -9,7 +9,7 @@ * * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/bootstrap/bootparse.y,v 1.87 2007/03/07 13:35:02 alvherre Exp $ + * $PostgreSQL: pgsql/src/backend/bootstrap/bootparse.y,v 1.88 2007/03/13 00:33:39 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -252,7 +252,7 @@ Boot_DeclareIndexStmt: LexIDStr($8), NULL, $10, - NULL, NIL, NIL, + NULL, NIL, false, false, false, false, false, true, false, false); do_end(); @@ -270,7 +270,7 @@ Boot_DeclareUniqueIndexStmt: LexIDStr($9), NULL, $11, - NULL, NIL, NIL, + NULL, NIL, true, false, false, false, false, true, false, false); do_end(); -- cgit v1.2.3
