Do you intend to ask what happens to logical slots invalidated (due to
say max_slot_wal_keep_size) on publisher? I think those should be
invalidated on standby too. Another thought whether there is chance
that the slot on standby gets invalidated due to conflict (say
required rows removed on primary)? I think in such cases the slot on
primary/publisher should have been dropped/invalidated by that time.
BTW, does the patch handles drop of logical slots on standby when the
same slot is dropped on publisher/primary?
