1cd6e04cd4 Fixed #18676 -- Allow fast-path deletion of objects 
Objects can be fast-path deleted if there are no signals, and there are
no further cascades. If fast-path is taken, the objects do not need to
be loaded into memory before deletion.

Thanks to Jeremy Dunck, Simon Charette and Alex Gaynor for reviewing
the patch.

99321e30ce Fixed #18306 -- Made deferred models issue update_fields on save 
Deferred models now automatically update only the fields which are
loaded from the db (with .only() or .defer()). In addition, any field
set manually after the load is updated on save.

29132ebdef Fixed #17788 -- Added batch_size argument to qs.bulk_create() 
The qs.bulk_create() method did not work with large batches together
with SQLite3. This commit adds a way to split the bulk into smaller
batches. The default batch size is unlimited except for SQLite3 where
the batch size is limited to 999 SQL parameters per batch.

Thanks to everybody who participated in the discussions at Trac.

b6c356b7bb Fixed #17485 -- Made defer work with select_related 
This commit tackles a couple of issues. First, in certain cases there
were some mixups if field.attname or field.name should be deferred.
Field.attname is now always used.

Another issue tackled is a case where field is both deferred by
.only(), and selected by select_related. This case is now an error.

A lot of thanks to koniiiik (Michal Petrucha) for the patch, and
to Andrei Antoukh for review.

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.

4c8f2dca21 Extensive copy-editing and cross-referencing in the queryset API docs. 
Been meaning to do this for a long time. Mostly, this is a lot of
additions of cross references. Within a particular section about foo() I
didn't cross-link foo() calls to itself, but everything else was
cross-linked to its main documentation.

4d21511961 Clarify the documentation around SQLite and case-sensitive string matching. 
This was still causing some confusion, so I rewrote the section in the
database notes to encompass both substring matching and non-ASCII
case-insensitive equality checks, as well as putting in a stronger
callout on the "contains" filter.

70e59aeaf8 Be very clear about when it's appropriate to use defer() and only(). 
I've been seeing a bit of over-reliance on defer() and only() in code
around the place and it's generally better modelled with normalised data
or shadow (unmanaged) models. This commit makes this position clearer.
