Sure, if they happened to have a concurrent index creation going when
they ran the check...  But what if they didn't and it only happened to
happen during the actual pg_upgrade?  I'm still not thrilled with this
idea of making the user have to abort in the middle to address something
that, really, isn't a big deal to just preserve and deal with later...Thanks,
