From ebb0a2014930034a89ae5f4953b52c9afbf585ae Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sun, 12 Nov 2000 20:51:52 +0000 Subject: Keep track of the last active slot in the shared ProcState array, so that search loops only have to scan that far and not through all maxBackends entries. This eliminates a performance penalty for setting maxBackends much higher than the average number of active backends. Also, eliminate no-longer-used 'backend tag' concept. Remove setting of environment variables at backend start (except for CYR_RECODE), since none of them are being examined by the backend any longer. --- src/backend/commands/dbcommands.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/backend/commands/dbcommands.c') diff --git a/src/backend/commands/dbcommands.c b/src/backend/commands/dbcommands.c index e2821d6237e..2442679250f 100644 --- a/src/backend/commands/dbcommands.c +++ b/src/backend/commands/dbcommands.c @@ -8,7 +8,7 @@ * * * IDENTIFICATION - * $Header: /cvsroot/pgsql/src/backend/commands/dbcommands.c,v 1.65 2000/11/08 23:24:24 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/commands/dbcommands.c,v 1.66 2000/11/12 20:51:50 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -225,7 +225,7 @@ dropdb(const char *dbname) /* * Check for active backends in the target database. */ - if (DatabaseHasActiveBackends(db_id)) + if (DatabaseHasActiveBackends(db_id, false)) { heap_close(pgdbrel, AccessExclusiveLock); elog(ERROR, "DROP DATABASE: database \"%s\" is being accessed by other users", dbname); -- cgit v1.2.3
