- 2PC is better than a standard transaction when dealing with multiple
servers as it can recover in some circumstances (but not all).

- 2PC (XA support as described by the X/Open group) is the only
implementation of distributed transactions supported by many third party
components -- that I'm aware of -- to the point where it is a part of
the Java Spec on dealing with distributed transactions.

- 2PC isn't very good in a number of circumstances, as such PostgreSQL
should avoid its use when PostgreSQL has a choice in the matter -- like
communication with other PostgreSQL servers.

This is a case of learning to speak Japanese because all of the people
you want to talk with only speak Japanese. It simply doesn't matter how
good Esperanto is.
