I've nearly finished off the patch Christopher distributed. Creates the
between node, and passes all regression tests except horology. I need
to update outfuncs and readfuncs -- but hope to fix the below first.
Seems I have a funny case left (Note the last comparison should be
false):
regression=# select 3 between 2 and 4;?column?
----------t
(1 row)
regression=# select 5 between 2 and 4;?column?
----------f
(1 row)
regression=# select 1 between 2 and 4;?column?
----------f
(1 row)
regression=# select 3 between 2 and 4 and 5 between 2 and 4;?column?
----------f
(1 row)
regression=# select 3 between 2 and 4 and 3 between 2 and 4;?column?
----------t
(1 row)
regression=# select 3 between 2 and 4 and 1 between 2 and 4;?column?
----------t
(1 row)
