Description:

The descriptions of the objoid and classoid fields in the documentation's
pg_description section are misunderstood. The description for objoid should
reference pg_class.oid, and the description for classoid should specify the
OID of pg_class, rather than "pg_class.oid."

Hmm, no, that's not right.  classid is supposed to refer to the
pg_class.oid value of the object type being commented on -- if you
comment on a table/view/etc then it's going to be the OID of pg_class.
But if you comment on a function, it's going to be the OID of pg_proc,
and so on.

As for objoid, that one is going to refer to the OID of the object being
commented on -- again, pg_class.oid if you are commenting on a
table/view/etc, but it could be pg_proc.oid if you're commenting on a
function, etc.
