Description

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.
