Enum from Postgres to Java using Hibernate

I'm trying to have a enum type on the database and convert it to java, I wrote a EnumUserType class to do the conversion, but it doesn't recognize the PGobject class.

public Object nullSafeGet(ResultSet rs, String[] names, SessionImplementor si, Object owner)
        throws HibernateException, SQLException {
    Object object = rs.getObject(names[0]);
    if (rs.wasNull()) {
        return null;
    }

    if (object instanceof PGobject) {
        //code doesn't reach this line
    }

    log.info(object.getClass()); // prints class org.postgresql.util.PGobject
    return null;
}

I checked and I have the exact same postgresql driver version. I saw this post: Java enum with Eclipselink. It is a solution that I will also try, but my main question is: apparently it is the same class, why it is not being recognized as such? Can I have two different classes with the same name and package? If I still have to use enums in Postgres, how can I fix it to properly map to my Java enum?

EDIT:

I tried to do a:

PGobject pg = (PGobject) object;

and it throws a class cast exception:

org.postgresql.util.PGobject cannot be cast to org.postgresql.util.PGobject

Thanks
