The DB2 documentation consistently refers to this column as "oid", but
there is no requirement to name it that way.
The SQL standard also contains this sentence:
Let OID be the name of the self-referencing column of S.
which refers to the thing defined in the example above, but "OID" is
just a placeholder here.
I think there was a mention of OIDs in the "SQL3" draft that eventually
became SQL99, but that's long past now. Current standards don't have
it, except in the, perhaps more generalized, form above.
