I think this point needs some thought. When you say 'all', how do you think it will help to support DDL replication for foreign tables, materialized views, views, etc where changes to such relations are currently not supported by logical replication? We should also think about initial sync for all those objects as well. -- With Regards, Amit Kapila.
