    Perhaps in ignorance, I have used the system assigned OID
    as a non-topical primary key. Instead of using the
    "PRIMARY KEY" key words, I explicitly created an index
    on the OID column.

    You can create a row of type OID. I have used them
    as foreign keys the times I used the OID field as the
    primary key.
