> Window queries that define a windowing clause that has a termination row often (though
not all) return incorrect results.  For example, from our test queries all of the following
return incorrect results:
> {code}
> select s, sum(f) over (partition by t order by b 
>        rows between current row and unbounded following) 
> from over100k;
> select s, avg(f) over (partition by b order by d 
>        rows between 5 preceding and current row) 
> from over100k;
> select s, avg(f) over (partition by bin order by s 
>        rows between current row and 5 following) 
> from over100k;
> select s, avg(d) over (partition by i order by f desc 
>        rows between 5 preceding and 5 following) 
> from over100k;
> {code}
