New description:

 Documentation has the wrong location of `ExtractYear`:

 https://docs.djangoproject.com/en/2.0/ref/models/expressions/#window-
 functions

 Example:

 {{{
 >>> from django.db.models import Avg, ExtractYear, F, Window
 Traceback (most recent call last):
   File "<input>", line 1, in <module>
     from django.db.models import Avg, ExtractYear, F, Window
 ImportError: cannot import name 'ExtractYear'
 }}}

 Should these functions be available from `django.db.models`? The module
 already contains quite a heavy load of imports....
