FYI there is a related discussion on another thread[1]; Now that
wal_level='replica' can dynamically become 'logical' WAL level
depending on the logical slot presence, there might be users who want
to allow physical replication while not for logical replication
(decoding) to avoid overheads due to logical WAL logging. Having
separate limits for logical slots and physical slots might help such
use cases too.
