> RealDistinctScalarAggregateStatistics derives from
> RealScalarAggregateStatistics
> RealDistinctScalarAggregateStatistics takes a constructor parm of rowsInput
> and forwards it to the super class's constructor, where it is stored for use
> by the class.
> However, the subclass mistakenly added a masked rowsInput field that is never
> set, and thus interferes with the proper use of the super class's rowsInput
> field.
> patch removed the erroneous subclass's field.
