Actually, wait a minute. Why wouldn't we need to lock the tuples on the standby just as we do on the primary? Sure, there can't be another user transaction modifying those tuples, but WAL replay could still modify them. Anyhow, I think that's beside the point. The documentation just says what Hot Standby does, not what it might do in a future release. And I don't think this patch changes that very much at all. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise Postgres Company -- Sent via pgsql-docs mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-docs
