Simon Charette daf2bd3efe Fixed #28107 -- Disabled grouping of selected primary keys for unmanaged models.
The grouping caused an issue with database views as PostgreSQL's query planer
isn't smart enough to introspect primary keys through views. Django doesn't
support database views but documents that unmanaged models should be used to
query them.

Thanks powderflask for the detailed report and investigation.

François Freitag 6b6be692fc Refs #16614 -- Prevented database errors from being masked by cursor close.
When an error occurred during the cursor.execute statement, the cursor
is closed. This operation did not fail with client-side cursors. Now,
with server-side cursors, the close operation might fail (example
below). The original error should be raised, not the one raised by
cursor.close(), this is only clean-up code.

For example, one can attempt to create a named cursor for an invalid
query. psycopg will raise an error about the invalid query and the
server-side cursor will not be created on PostgreSQL. When the code
attempts to cursor.close(), it asks psycopg to close a cursor that was
not created. pyscopg raises a new error: psycopg2.OperationalError:
cursor "_django_curs_140365867840512_20" does not exist.

François Freitag f3b7c05936 Refs #16614 -- Made QuerySet.iterator() use server-side cursors on PostgreSQL.

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