> The query:
> select s, i, avg(d) / 10.0 over (partition by s order by i) from over100k;
> runs (and produces meaningless output).
> Over should not allow the arithmetic expression.  Only a UDAF or PTF function should
be valid there.  The correct way to write this query should be 
> select s, i, avg(d) over (partition by s order by i) / 10. 0 from over100k;
