Lookups on ExtractYear on a DurationField fails because ExtractYear has an
optimisation where it compares the source date with a range of dates.
{{{
class MyModel(models.Model):
duration = models.DurationField()
MyModel.objects.annotate(year=ExtractYear('duration')).filter(year__gt=1)
}}}
The queryset generated looks like
{{{
SELECT * FROM mymodel WHERE duration > '0001-01-01'
}}}
and it fails because interval are not comparable with dates
