Of course, the chances of doing anything more than extremely-marginal
kluges without breaking on-disk compatibility are pretty tiny.  Given
where we are at the moment, I see no appetite for forced dump-and-reloads
for several years to come.  So I don't foresee that anything is likely
to come of such efforts in the near future.  Even if somebody had a
great idea that would make things smaller without any other penalty,
which I'm not sure I believe either.
