Description

If you've got a queryset that has had select_related called on it (maybe passed to you from some other code you don't control) there's currently no documented way to clear out select_related.

One possible API is .select_related(None), which mirrors how .defer() works.

The combination of this and #16855 would make .select_related() and .defer() more consistent with each other, which would be nice.

There was a clear consensus on this API in #django-dev.

For anyone reading this, the undocumented hacky way to do this is:

qs.query.select_related = False
