> 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.
