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.
