> {{queryPlan..getProjector().getEstimatedRowByteSize()}} returns "0" for a
> query {{SELECT A_ID FROM TABLE}} where {{A_ID}} is Primary Key. Same is the
> case for the query {{SELECT A_ID, A_DATA FROM TABLE}} where {{A_DATA}} is a
> non key column. Assuming that the method is meant to return the estimated
> number of bytes from the query projection the returned value of 0 is
> incorrect.
