Note that it's even possible that the old system had a card with write caching enabled, but *no* battery backed cache. That's crazily dangerous, but does get you the speed benefits of write caching without the need for a BBU. I only mention this to help explain a possible performance difference - you should NEVER do this if you care about your data. -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
