ok so I am totally stumped here, I have created some tables in postgres 8.3 (and JPA, with hibernate as the provider) and some entities, one of my entities has a column of type "game_type" which i created in postgres as follows

Code:
CREATE TYPE game_type AS ENUM('forward','backward');


so i created an enum and set the @Enumerated in the anotations like I would in mysql, but when I try to select from the table i get the following error

Code:
java.lang.ClassCastException: org.postgresql.util.PGobject cannot be cast to java.lang.String
