> The diff file in the attachment can fix this problem. I'm confused. RelationBuildDesc doesn't open pg_class and shouldn't be responsible for closing it either; both of those things happen in ScanPgRelation, leaving no apparent scope for a leak such as you suggest. Moreover, there's no variable named pg_class_relation in this whole file, so your patch wouldn't even compile. Could you show us a test case that provokes the warning you see? regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
