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).
Cheers,
Neil
