    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.
