This monster of a patch is the result of Alex Gaynor's 2009 Google Summer of Code project.
Congratulations to Alex for a job well done.
Big thanks also go to:
* Justin Bronn for keeping GIS in line with the changes,
* Karen Tracey and Jani Tiainen for their help testing Oracle support
* Brett Hoerner, Jon Loyens, and Craig Kimmerer for their feedback.
* Malcolm Treddinick for his guidance during the GSoC submission process.
* Simon Willison for driving the original design process
* Cal Henderson for complaining about ponies he wanted.
... and everyone else too numerous to mention that helped to bring this feature into fruition.

We need to know the number of rows that are matched by an UPDATE query,
not just the number of rows that are changed. In the relatively unlikely
event that somebody was using Django's cursor proxy and relying on the
previous behaviour, well, that isn't the case any longer. We need to
this version.
Thanks to Daniel Tang for pointing out the solution here.

This is backwards-compatible but will likely break third-party database backends. Specific API changes are:
* BaseDatabaseWrapper.__init__() now takes a settings_dict instead of a settings module. It's called settings_dict to disambiguate, and for easy grepability. This should be a dictionary containing DATABASE_NAME, etc.
* BaseDatabaseWrapper has a settings_dict attribute instead of an options attribute. BaseDatabaseWrapper.options is now BaseDatabaseWrapper['DATABASE_OPTIONS']
* BaseDatabaseWrapper._cursor() no longer takes a settings argument.
* BaseDatabaseClient.__init__() now takes a connection argument (a DatabaseWrapper instance) instead of no arguments.

that happens with MySQL when a "GROUP BY" clause is included. This is a
backend-specific operation, so any other databases requiring similar
encouragement can have a function added to their own backend code.

convert it to an IntegrityError, which seems like the more natural case (and is
consistent with other backends). This makes exception handling in Django much
easier.
The solution is extensible for any other error codes we may wish to add going
forwards.

This effectively reverses the change in [7798]. It was proving too difficult to
successfully manage all the side effects here and provide a satisfactory
solution for everybody. Many thanks to arne, Martin von Löwis and, particular,
Karen Tracey, for doing a lot of research and proto-patches here to establish what was possible and practical.
This is backwards incompatible if you were relying on the behaviour after
[7798]. The docs have been updated to indicate the solution.

loading/saving interactions with the databases into django.db.backend. This
helps external db backend writers and removes a bunch of database-specific
if-tests in django.db.models.fields.
Great work from Leo Soto.

This is a backwards incompatible change if you were relying on 'exact' being
case-insensitive. For that, you should be using 'iexact'.

This patch simplifies a bunch of code for all backends and removes some
duplicate index creation for MySQL, in particular (versions 4.x and later).
Patch from Nis Jørgensen.
Fixed#5671, #5680, #7170, #7186.

database level. Also worked around the fact that MySQL (and maybe other
backends we don't know about) cannot select from the table they're updating.
Fixed#7095.

database backends differently now. Which meant the MySQLdb version check was
being swallowed. Changed the exception type to ensure this is percolated
correctly. Patch from Ramiro Morales.

references, for all tables, until after the table has been created. This means
that when using the InnoDB storage engine, true foreign key constraints are
created (inline "REFERENCES" are ignored by InnoDB, unfortunately).
Fully backwards compatible.
