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 .

Thanks to akaariai for the report and tests.
No tests have been added, since unittests for termination are basically
impossible, and the failure condition will take down the developer's machine
in this case. It has been tested against the cases in #17014 .
