The complexity is that pg_upgrade does create the data, but relies on a
schema-only dump. So we'd need to at least account for that somehow,
either with a separate stats-only dump, or make a special case in
binary upgrade mode that dumps schema+stats (and resolves the CREATE
INDEX issue).

Would there be a significant cost to just not doing that? Or are you
suggesting that we special-case the behavior, or turn it off during
restore with a GUC?
