    Answering both you and Mike: Yes, it _is_ a bug in EOF. Yes, it
    should go back to Pierre. It has been broken since 4.01 IIRC. SQL
    generation for single table inheritance is just broken. Hmmmm, IIRC,
    it is also broken for the other ones too as it generates impossible
    FK constraints when a relationship references an entity that can be
    in one of several tables.
