> Aaaargh! No, it doesn't. It means NULL. Nothing else. Well, x = UNKNOWN doesn't make any sense... the answer is UNKNOWN. x IS UNKNOWN does make sense, the answer is true or false. Replace UNKNOWN with NULL... Actually it means what the DBA wants it to mean (which opens the door to many a misguided design...) I hereby light a candle to the pgsql designers who didn't inflict 00-00-0000 00:00:00 upon us besides NULL dates.
