The first connects as user foo to the database FOO, while the other
connects as the current user (postgres, after sudo).

If you do have a system user foo, you could sudo to it instead of
# sudo -u foo psql -f central.sql -q FOO

You're missing lines for local, as psql uses by default unix sockets (as
John Summerfield pointed out):
local all all trust

Note that this isn't very secure, as any user in the host can presume to
be any other user, so you should change trust to md5 and make sure you
have passwords defined for all postgres users.
