More fixing of PostgreSQL < 8.2 problems with the psycopg2 backend.
...
Affects the postgresql_psycopg2 backend only. We now don't use the
"RETURNING" syntax in SQL INSERT statements unless it's required by the
autocommit behaviour. This fixes an edge-case that could cause crashes
with earlier PostgreSQL versions, but the broader problem remains to be
fixed (which is #10509 ).
Fixed #10467 . Refs #10509 .

Fixed #10467 -- Fixed generated INSERT SQL for PostgreSQL 8.1 and earlier.
...
I introduced a bad regression in r10029, forgetting to check that some
syntax was supported. For now, you can't use autocommit=True with 8.1
and earlier (it's still available for later versions). I'll fix the
broader issue later and re-enable it for those versions, but I want to
get the SQL regression for the default path out of the code right now.

Fixed #10459 -- Refactored the internals of database connection objects so that connections know their own settings and pass around settings as dictionaries instead of passing around the Django settings module itself. This will make it easier for multiple database support. Thanks to Alex Gaynor for the initial patch.
...
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.

Added savepoint support to the transaction code.
...
This is a no-op for most databases. Only necessary on PostgreSQL so that we can
do things which will possibly intentionally raise an IntegrityError and not
have to rollback the entire transaction. Not supported for PostgreSQL versions
prior to 8.0, so should be used sparingly in internal Django code.
