Upstream support for PostgreSQL 11 ends in November 2023. Django 4.2 supports
PostgreSQL 12 and higher.
Setting ``update_fields`` in ``Model.save()`` may now be required
-----------------------------------------------------------------
In order to avoid updating unnecessary columns,
:meth:`.QuerySet.update_or_create` now passes ``update_fields`` to the
:meth:`Model.save() <django.db.models.Model.save>` calls. As a consequence, any
fields modified in the custom ``save()`` methods should be added to the
``update_fields`` keyword argument before calling ``super()``. See
:ref:`overriding-model-methods` for more details.
