17796	Aggregating an IntegerField returns Decimal from MySQL	adsva	nobody	"{{{
>>> MyModel.objects.get(pk=1).my_int_field
>>> 581L
>>> MyModel.objects.filter(pk=1).aggregate(Sum('my_int_field'))
>>> {'my_int_field__sum': Decimal('581')}
}}}

The aggregate used to return an integer until recently. 

It looks like changeset:17588 added a convert_values-method to the !DataBaseOperations class for the MySQL backend, but since it only handles Boolean conversions, it should probably call the parent's convert_values if it's not a boolean?
