This is not a security hole in dblink, it is a security hole in your
pg_hba.conf setup. Don't use trust authentication.

That seems completely impractical. In the first place, it's not a
reasonable default (there's no good reason to assume that the remote
DB has the same users as the local), and in the second place dblink
cannot get at the user's password. (We *would* have a security hole
if it could.)
