I see. Yes, the slot on the old primary would keep retaining WAL, and the promoted standby would stop sending feedback once it has switched to a new timeline so that should work. Don't forget to drop the drop on the old primary after pg_rewind has been run, you don't want to bloat its pg_xlog with useless data. -- Michael -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
