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.

The documentation in this tree is in plain text files and can be viewed using
any text file viewer.

Technically speaking, it uses ReST (reStructuredText) [1], and the Sphinx
documentation system [2].  This allows it to be built into other forms for
easier viewing and browsing.

To create an HTML version of the docs on a Unix machine (Linux or Mac):

* Install Sphinx (using ``easy_install Sphinx`` or some other method)

* In this docs/ directory, type ``make html`` (or ``make.bat html`` on
  Windows) at a shell prompt.

The documentation in _build/html/index.html can then be viewed in a web browser.
