If we're going to do that we should do it *now*, not later, because
right now is when we have a bug that we could actually save some effort
on.  In practice, since we have not ever suggested that we were actually
going to remove the feature, I don't believe that we can do that.  Not
in 8.4, and not in 8.5 or any other near-future release either.

The larger point though is that unless we restructure the system to the
point of not using OIDs in system catalogs ... which ain't happening
... the amount of code we could save by removing OIDs for users is
vanishingly small.  Probably on the rough order of 100 lines, and about
the same in documentation.  (We couldn't, for instances, stop
documenting that OIDs exist.)  Doesn't really seem worth breaking
applications for, even deprecated ones.
