A new implementation --- I don't think this is usable as is (at least
not the parser part; I haven't studied the executor part closely yet).
For one thing, it ignores the agreed-on TODO items:
* Add SQL99 WITH clause to SELECT
* Add SQL99 WITH RECURSIVE to SELECT
We had the RHDB project meeting today and agreed that we'd work on this
(among other things) for 7.4. You can put down Fernando Nasser and me
as the responsible developers for these TODO items.
