Maybe he knows of some fundamental flaws with his implementation ?
Why else does he think that it will not be accepted ?
He could at least try to submit it again, once it is past the "almost"
part :)
BTW, I also "almost" got a working implementation of SQL99 recursive
queries (at least it parsed the syntax ;), but gave up due to lack of
time and also because the SQL99 recursive queries are a desceptively
complex beast which I was unable to fully understand from the specs, at
least the part beyond the simple parent-child tree queries.
And the simple parent-child tree queriest are now doable using
set-returning functions.
