The odds are quite high. Couldn't we introduce a new wal_level value instead? wal_level = logical_only I think this thread shows that logical replication no longer is a superset(?) of physical replication. I thougt that we might be able to change wal_level from scalar to bitmap but it breaks backward compatibility.. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
