> have you had any power events? hard shutdowns, etc? I wonder if the problem is in the clog files, and not the heap itself. Nothing unusual for as long as I can tell. Reminder that as long as I don't restart the primary's pg process, everything works fine (secondary's data is intact). It's as if stopping/starting the primary causes a shipped wal file to be corrupt or contain duplicated data then processed by the secondary. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
