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...

Cheers,
D
