Kind people, I just ran across this, and was wondering whether it's worth a back-patch. The interval type has an aggregate for average (AVG), but not one for standard deviation (STDDEV) or variance (VARIANCE).
Is this a bug? Is there some problem with defining variance over intervals? TIA for any pointers in the right direction...
