aggregate(Sum('x')) returns None

[kesmit]

I've noticed that the Sum('x') function will return None if there are
no records in the queryset. This doesn't seem correct to me.
Shouldn't Sum always return a Decimal? It makes it difficult to
compute more complex expressions when you can't depend on a number
being returned.

Agree, i think sum must return decimal. Same problem with me.

None != 0

If no rows were encountered, then None should be returned, because there was no data to aggregate, thus how can it logically come back with 0?

I'm -1 on this
