Sure, there's an argument to be made for that.  But pg_dump (or in this
case, it would more be pg_restore I guess) also doesn't run ANALYZE or
generate a script to do that, does it? ISTM that we have already decided
that pg_upgrade has a different requirement on providing those things,
whereas pg_dump/pg_restore is more of a low-level tool where people have to
figure more things out themselves.
