I can't speak for Arch Linux' upgrade setup, but going from 8.4 -> 9.0
requires that the data directory either be dumped/recreated, or ran
through the new upgrade process (which (as yet) I have no experience
with).

If the Arch Linux stuff doesn't do that automatically, then you'll have
to do it manually.
