How about a 'localhost' keyword which would match the local host 
according to whatever ip stack(s) is (are) running? e.g.
 localhost all all trust

Then we wouldn't have to play initdb tricks, but we would have to make 
postmaster a bit smarter.

Downside is pg_hba.conf seems to be rapidly becoming more complex.
