No.

OK. But why not views ? That's exactly the use case where views should
be used in PostgreSQL. Using views you need not modify anything in
your class.
Alternative solution:
Change your class (if possible) to have the members name, version,
release and add a method getFullName() to the class. (I would never
do this but use views.)
