My understanding is that 2PC is one way to implement multi-master replication. If that's what you're referring to, then I'm not sure I see the point: the multi-master replication project (pgreplication) doesn't use 2PC, due to apparent scalability problems (not to mention that it also uses a separate channel for communications between backends on different nodes).
