No, we're not that rigid about it. The commitfest mechanism is really
mostly meant to ensure that every submission does get looked at within a
reasonable amount of time and doesn't get forgotten about. (We do tend
to be willing to tell new patches they've got to wait till the next fest,
but that's mainly when we're already feeling overloaded by what's in the
current queue.) In this case it would be nonsensical to consider only
Peter's submission and not Joy's, because part of the issue is whether
one's better than the other.

Well, at the point we're at here, it's probably not that important exactly
which version of a patchset you're looking at; I'd take the latest.

Actually, we *do* require that, mainly as a formality to show that the
author intended to submit it for inclusion in Postgres. (We don't want
people coming back later and saying "hey, you ripped off this code from
my github repo without my permission".) If we were seriously considering
adopting Joy's version then that would have to happen before anything got
merged. But at this point it seems like we're in a very exploratory
phase and there's no need for legal niceties yet.

Yup, that's how we roll ... it's ancient habit from before there was
such a thing as git, let alone github, but we've not seen fit to change.
It does have the advantage that it's about equally amenable to high-
level discussions and line-by-line issues.
