> Currently user need to do following:
> {noformat}
> select s, sum(b) over (distribute by i sort by si rows between unbounded preceding and current row) from over100k;
> {noformat}
> but sql spec allows following as well:
> {noformat}
> select s, sum(b) over (distribute by i sort by si rows unbounded preceding) from over100k;
> {noformat}
> In such cases {{current row}} should be assumed implicitly.
