I did some cross version tests on patch v95 (publisher is PG14 and subscriber is PG15, or publisher is PG15 and
subscriberis PG14; set two_phase option to on or off/default). It worked as expected, data could be replicated
correctly.

Besides, I tested some scenarios using synchronized replication, it worked fine in my cases.

So this patch LGTM.
