Comment:
I am sorry the discussion drifted off topic. The system is **NOT**
working as intended. The ORM is explicitly blocking functionality
supported by the database, and lying about the reason. If the reason is
the Django default DateTime object refuses to ever store timezones in the
database, then it should say that at least.
This is further exacerbated by the part where PostgreSQL's documentation
says that it just silently converts all DateTimes to UTC prior to saving.
I have not confirmed, but that would also silently mean that any
PostgreSQL user with `USE_TZ = False` might be in for a surprise.
I can see two approaches to solving this bug.
* The SQLite backend's `adapt_datetimefield_value` is adjusted to support
timezone aware DateTimes when `USE_TZ = False`.
* Django as a whole should declare that when `USE_TZ = False`, a user may
never save a Timezone aware DateTime.
* That would involve adding checks to
`BaseDatabaseOperations.adapt_datetimefield_value` and the PostgreSQL
backend.
