Two possibilities:

1. You're using a couple of different cases in the above example.
PostgreSQL is case-sensitive. What interface program are you using?
What OS? From the error messages, it looks like your commands are being
lower-cased by the interface or data transport, which would cause
Postgres not to recognize the field names.
a. Try you commands from PSQL on the Database server, making sure that
your case is the same as the table definition.
b. If you can down the DB for an hour, try re-naming one of the ID
fields in lower case (one that isn't foriegn keyed, of course).

2. It's possible that defining these rows as type OID requires some
special reference syntax. If so, hopefully someone on the list will
come forward.
