pg_createsubscriber currently always sets up logical replication with two-phase commit disabled. Improving that is not going to happen for v17. In the meantime, document the deficiency, and adjust pg_createsubscriber so that it will emit a warning if the source installation has max_prepared_transactions > 0.
