Well, Greg had left further squeezing of numerics as an open item in his
varlena patch, so it's not totally unreasonable to consider a patch for
that now --- as long as it's pretty small and simple.
I agree that in-place upgrade is a pipe dream until we see someone
actually step forward and do the work to build a usable pg_upgrade
utility.
If nothing else, we should consider swapping the n_sign_dscale and
n_weight fields now, since that would enable upward-compatible
implementation of these ideas later. Otherwise any such patch
would probably get rejected if pg_upgrade did happen to emerge out
of nowhere.
