Unfortunately, I do not know the planned release date, and would probably not have the liberty to tell you, if I had known it. :-)

Until then, a possible work-around that may work is "SELECT COUNT(DISTINCT <all pkcols>) ...", or if there is an indexed column with no NULL values, you can try "SELECT COUNT(<col>) ..."
