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/commands/dbcommands.c | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) (limited to 'src/backend/commands/dbcommands.c') diff --git a/src/backend/commands/dbcommands.c b/src/backend/commands/dbcommands.c index 63e15e505b7..de4b239893a 100644 --- a/src/backend/commands/dbcommands.c +++ b/src/backend/commands/dbcommands.c @@ -13,7 +13,7 @@ * * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/commands/dbcommands.c,v 1.192 2007/02/09 16:12:18 tgl Exp $ + * $PostgreSQL: pgsql/src/backend/commands/dbcommands.c,v 1.193 2007/03/13 00:33:39 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -97,9 +97,6 @@ createdb(const CreatedbStmt *stmt) int encoding = -1; int dbconnlimit = -1; - /* don't call this in a transaction block */ - PreventTransactionChain((void *) stmt, "CREATE DATABASE"); - /* Extract options from the statement node tree */ foreach(option, stmt->options) { @@ -545,8 +542,6 @@ dropdb(const char *dbname, bool missing_ok) Relation pgdbrel; HeapTuple tup; - PreventTransactionChain((void *) dbname, "DROP DATABASE"); - AssertArg(dbname); if (strcmp(dbname, get_database_name(MyDatabaseId)) == 0) -- cgit v1.2.3
