Ramiro Morales 287565779d Added support for modifying the effect of ``DISTINCT`` clauses so they ... only consider some fields (PostgreSQL only). For this, the ``distinct()`` QuerySet method now accepts an optional list of model fields names and generates ``DISTINCT ON`` clauses on these cases. Thanks Jeffrey Gelens and Anssi Kääriäinen for their work. Fixes #6422. git-svn-id: http://code.djangoproject.com/svn/django/trunk@17244 bcc190cf-cafb-0310-a4f2-bffc1f526a37		2011-12-22 20:42:40 +00:00
