in PostgreSQL from the iterator method, and Anssi Kääriäinen and Kevin
Turner for their previous work. Also Simon Charette and Tim Graham for

* Added the :setting:`TEST['TEMPLATE'] <TEST_TEMPLATE>` setting to let
PostgreSQL users specify a template for creating the test database.
* :meth:`.QuerySet.iterator()` now uses :ref:`server-side cursors
<psycopg2:server-side-cursors>` on PostgreSQL. This feature transfers some of
the worker memory load (used to hold query results) to the database and might
increase database memory usage.

* Renamed the ``ignores_quoted_identifier_case`` feature to
``ignores_table_name_case`` to more accurately reflect how it is used.
* The ``name`` keyword argument is added to the
``DatabaseWrapper.create_cursor(self, name=None)`` method to allow usage of
server-side cursors on backends that support it.
Dropped support for PostgreSQL 9.2 and PostGIS 2.0
