(Naturally I'm also in the process of testing). I can't see why it wouldn't. The WAL/replication mechanism works at such a low level that it has no idea whether an update to pg_attribute originated in an official DDL command or a manual UPDATE of the catalog. I think you should be more worried about fat-fingering the update than whether it will be replicated correctly. But, of course, testing is always a good idea ;-) regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
