Description (last modified by Flávio Juvenal)

Looks like the solution for "#11256 Fail loudly and clearly when an Annotation alias matches a field name" doesn't consider foreign keys attnames, e.g. {{author_id}}.

Here's a failing test, add it to aggregation_regress/tests.py:

def test_fk_attname_conflict(self):
    msg = "The annotation 'contact_id' conflicts with a field on the model."
    with self.assertRaisesMessage(ValueError, msg):
        Book.objects.annotate(contact_id=F('publisher_id'))
