Well, I wasn't responding to you - I was responding to Josh.
Regardless of the merits of redesigning this particular data type, I
think it's important for us to cultivate a mindset of figuring out how
we can make gradual improvements to the on-disk format without
earth-shattering consequences for pg_upgrade.  Mind you, I don't
currently have the time to hack on this for, uh, more or less the
reason you state.  But if my boss told me he double my pay if I got it
done, I wouldn't tell him it's technically impossible.
