``datetime_extract_sql()``, etc.
* ``DatabaseOperations.return_insert_id()`` now requires an additional
``field`` argument with the model field.
* Entries for ``AutoField``, ``BigAutoField``, and ``SmallAutoField`` are added
to ``DatabaseOperations.integer_field_ranges`` to support the integer range
validators on these field types. Third-party backends may need to customize
the default entries.
* ``DatabaseOperations.fetch_returned_insert_id()`` is replaced by
``fetch_returned_insert_columns()`` which returns a list of values returned
by the ``INSERT … RETURNING`` statement, instead of a single value.
* ``DatabaseOperations.return_insert_id()`` is replaced by
``return_insert_columns()`` that accepts a ``fields``
argument, which is an iterable of fields to be returned after insert. Usually
this is only the auto-generated primary key.
