Do select * from ONLY DObject.

The constraint currently only goes to DObject, records that are actually
in DObject and not any tables derived from it. This is one of the
deficiencies I was trying to refer to in the previous message. As a note,
your primary keys will also not work to prevent duplicates of objectid
between subclasses of DObject currently, and I'm not sure whether that
matters to you:

insert into dmessage (who, privilege, objectid, objecttype, status,
aname,sender,receiver) values (-2,-2,33,13,301,'name',-2,-2);

select objectid from dobject;objectid
----------      34      35      33      33
(4 rows)

Inheritance needs alot of work. :(
