Hm?  I don't think that an initdb here would have any impact on whether
we can call the next drop RC1 or not.  We're talking about removing a
single built-in entry in pg_proc --- it's one of the safest changes we
could possibly make.  The only argument I can see against it is not
wanting to force beta testers through an initdb.  But it seems like that
might actually be a positive thing not a negative one, in this cycle,
because we're trying to get test coverage on pg_upgrade.
