Why is it a bad thing to call the column "stddev_samp" analog to the
aggregate function or make a note in the documentation, that the
sample stddev is used to compute the solution?
I think you are making a mountain out of a molehill, frankly. These
stats are not intended as anything other than a pretty indication of the
shape, to see if they are significantly influenced by outliers. For any
significantly large sample size the difference will be negligible.
But I will add a note to the documentation, that seems reasonable.
