This patch introduces the '--enable-two-phase' option to the 'pg_createsubscriber' utility, allowing users to enable two-phase commit for all subscriptions during their creation. Note that even without this option users can enable the two_phase option for the subscriptions created by pg_createsubscriber. However, it requires the subscription to be disabled first which could be inconvenient for users. When two-phase commit is enabled, prepared transactions are sent to the subscriber at the time of 'PREPARE TRANSACTION', and they are processed as two-phase transactions on the subscriber as well. If disabled, prepared transactions are sent only when committed and are processed immediately by the subscriber.
