With Hibernate's Session object, sure - you can getConnection() from the
session, then reflectively access the methods of the underlying
PGConnection via C3P0. It's ugly but works.
I was about to say that you can't get the Connection object from
EntityManager if using Hibernate, when I realised you can call
EntityManager.getDelegate() to get the Session, then getConnection() on
that. I have no idea how I missed getDelegate() before.
Sigh. Guess you *can* just use C3P0's reflective calls even if using JPA.
