Please note as well that if hot_standby_feedback is enabled, the
cleanup done by VACUUM on the primary is influenced as well so as
tuples that a standby may need to avoid conflicts for its transactions
are not removed. So VACUUM may result in less cleanup depending on the
read load on the standby.Also that replication slots provide standby feedback and may further delay vacuuming when the standby is offline.--
