If I want to develop a portable application or I want to port an
application, then I am of course only going to use portable constructs,
that is, tables and views, and possibly sequences. I'm not talking theory
here -- I've actually done it and made several changes to pg_dump along
the way to make the output portable. This is an actual feature that is
being destroyed.

I'm sure there are other ways to phase out OIDs in dumps. For example, we
could set the default mode at the top (easily deleted, much safer than
running a global search and replace) and then add WITH/WITHOUT OIDS only
to those tables that deviate from the default.
