    src/include/utils: date.h timestamp.h

Log message:
    Create crosstype comparison operators for date vs. timestamp and date
    vs. timestamptz.  This allows use of indexes for expressions like
    datecol >= date 'today' - interval '1 month'
    which were formerly not indexable without casting the righthand side
    down from timestamp to date.
