Hi Dyre,

I had a quick look at the patch, and there was one thing I didn't
quite understand in IndexToBaseRowNode.init(). When heapReferencedCols
is null, allReferencedCols is also set to null. Intuitively, I would
say allReferencedCols should be equal to indexReferencedCols in that
case (since A U NULL == A). Or maybe indexReferencedCols is always
null when heapReferencedCols is null?

Also, in the same method, is the "return" necessary? If it isn't, I
think it would be better to remove it since it could easily be
overlooked by someone who adds more code below the if-block later.
