hot_standby_feedback needs to be enabled at all times in logical decoding so as the node does not remove rows that are still needed for the decoding, and a VACUUM passing by with a minimal xmin too high would cause inconsistent decoded data. -- Michael -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
