If you don't still have the correct contents on the master, I think the only way to recover is to take a fresh base backup so you can make the slaves roll forward from a point later than this log segment. There's no reason to suppose that there's data corruption on the master, just bad data in the WAL archive. You'd probably be well advised to look closely at your WAL archiving script to see if it has any race conditions that might be triggered by very fast generation of WAL. > Also, one additional question.

Just ignore that, it's cosmetic (the file isn't supposed to exist). regards, tom lane -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
