This is a constraint of streaming replication, and listed as a TODO item.

   Have pg_hba.conf consider "replication" special only in the database field
       * http://archives.postgresql.org/pgsql-hackers/2010-10/msg00632.php

I suspect this is going to trip a lot of people up.  We could just
document it and tell people that if they want to use 'replication' as
a username, they'd better quote it in pg_hba.conf.
