If this is all you have to work with, you can probably use pg_resetxlog to wipe out the broken WAL data and then you'll be able to start the database, but expect to find some amount of data corruption if you go that way. A dump and reload would probably be wise at that point. 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
