Oh, sorry for the mistake, it is about standby of course. > BTW I am wondering if it is possible > to achieve the same situation by pg_rewind and standby promotion… Looks like it is impossible, because wal_log_hints is required in order to use pg_rewind. It is possible to achieve a situation with some additional LP_DEAD on standby compared to the primary, but any change on primary would cause FPI, so LP_DEAD will be cleared. Thanks, Michail.
