New description:

 After the introduction of the `Lookup` API in Django 1.7, I believe that
 `django.contrib.postgres` could benefit from some custom lookups based on
 the unaccent extension of PostgreSQL (see
 http://www.postgresql.org/docs/9.3/static/unaccent.html). That kind of
 feature would be very helpful for a lot of people in latin countries, and
 the existing solutions seems not very clean (and do not make use of the
 new API).
