Can't speak to other JPA implementations, but with EclipseLink logging
you get potentially a multitude of information. Query text and bind
parameters are already available at FINE, and there's still FINER and
FINEST.

JPA is also well provided with its own exception classes: there are ten
or so subclasses of javax.persistence.PersistenceException. If something
underneath at the JDBC level throws a java.sql.SQLException you'll see
that too.
