I think that's a restriction that doesn't make much sense. What if you
want to dump the data as fast as possible to get things up in another
machine/datacenter/whatever after a fault? Uh wait, parallel dump won't
work with single user mode.
This isn't strengthening security. This is making something far too
complicated (pg_hba.conf) into something even more complicated, because
suddenly even the most basic things only work in some environments. If
you want to improve security significantly, make it easier to configure
authentication/authorization. That's one of the hardest parts of
postgres.
