We seem to be split on the idea of having "Has OIDs" display only when
the oid status of the table does not match the default_with_oids
default.

I am attaching a patch which implements this, but given no consensus, I
will not apply it unless we can be more definite.

My motivation was that "Has OIDs" was important when we stopped having
an oid column by default, but at this point many users don't even know
what OIDs are and the line is potentially confusing and mostly useless.
