Server-side cursors on PostgreSQL
---------------------------------
The change to make :meth:`.QuerySet.iterator()` use server-side cursors on
PostgreSQL prevents running Django with `pgBouncer` in transaction pooling
mode. To reallow that, use the :setting:`DISABLE_SERVER_SIDE_CURSORS
<DATABASE-DISABLE_SERVER_SIDE_CURSORS>` setting (added in Django 1.11.1) in
:setting:`DATABASES`.
See :ref:`transaction-pooling-server-side-cursors` for more discussion.
