Perhaps a quick process flow would help clarify: Scenario 1 (no errors): a) create warm standby and let run throughout the day (works great) b) at the end of the day, trigger the secondary and run a reindex for testing (no errors) Scenario 2 (errors): a) create warm standby and let run throughout the day (works great) b) nightly backup: shutdown pg on primary, do a file system copy (for backup later), start pg again on primary c) the next morning, trigger the secondary and run a re-index for testing (ERRORS as described in thread) Side note: the data copied in 2.b is fine and also passes a full re-index. Scenario 3 (work around - not a very good one): a) create warm standby and let run throughout the day (works great) b) nightly backup: shutdown pg on primary, do a file system copy (for backup later), start pg again on primary c) the next morning, re-create the warm standby (this is where I may have confused you with doing a pg_start_backup after nightly backups) Thanks! -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
