I notice that you avoid saying "yes, I agree we should remove the two checks". I will add code to make a shutdown checkpoint be a valid starting place for Hot Standby, as long as there are no in-doubt prepared transactions. That way we know there are no xids still running and no locks, without needing to write a record to say so. -- Simon Riggs www.2ndQuadrant.com -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
