28815	Incorrect ExtractYear imports in Window functions docs	benjaoming	nobody	"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....
