User user = new User();
user.setGender('M');
Transaction t = HibernateTest.getSessionFactory().getCurrentSession()
.beginTransaction();
HibernateTest.getSessionFactory().getCurrentSession().save(user);
t.commit(); //Saved OK.

user = new User();
user.setGender('\1');
t =
HibernateTest.getSessionFactory().getCurrentSession().beginTransaction();
HibernateTest.getSessionFactory().getCurrentSession().save(user);
t.commit(); // Also saved OK.

user = new User();
user.setGender('\0');
t =
HibernateTest.getSessionFactory().getCurrentSession().beginTransaction();
HibernateTest.getSessionFactory().getCurrentSession().save(user);
t.commit(); // Failed. That means the '\0' is not supported by the jdbc of
postgresql.
