Description
ArrayField allows lookups by index when filtering, e.g.
qset.filter(arr__0=foo)
but things like
qset.values('arr__0')
qset.aggregate(Max('arr__0')
are not allowed.
I'm not sure if this counts as a feature request or bug. From a cursory look at the Django source it seems that this functionality may not be compatible with the way Django handles lookups outside of .filter().
