Thanks Lew.

As far as I can tell, postgres does not support two-phase commit either.
This todo list updated yesterday notes that two-phase commit as a pending
"exotic" feature:

http://developer.postgresql.org/todo.php

Firebird apparently does support two-phase commit, so if this feature is
needed, it looks like Firebird is the way to go.

As for referential integrity and transaction support, recent releases of
MySQL support both.
