Well, at the very least, you need to guarantee that the standby is caught up - i.e. that it replayed all the WAL records that were generated on the master before it was shut down for the final time. I don't think that telling the user that they must be sure to do that is sufficient - you need some kind of built-in safeguard that will complain loudly if it's not the case. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
