New rangejoin patch attached.
I had previously attempted to make this work well for multiple range
join keys, but this patch implements single rangejoin keys only, and
the rest of the rangejoin clauses are effectively just rechecks. I
believe it can be made effective for multiple rangejoin keys, but at
the cost of additional complexity which is neither justified nor
implemented at this point.
Regards,
Jeff Davis
