If you're using XA transactions in a Java EE context, what you want is
probably an EJB3 with
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
which will force the EJB business method(s) so annotated to run in their
own independent transactions. Note that these transactions will *NOT* be
able to see any uncommitted changes from your main transaction, they're
completely independent and behind the scenes with PostgreSQL are
actually new connections to the server.
