If we're going to do it can we please come up with something more

before moving to such a release.
The probability that we would actually *remove* that behavior of OFFSET
0 is not distinguishable from zero. I'm not terribly excited about
having an alternate syntax to specify an optimization fence, but even
if we do create such a thing, there's no need to break the historical
usage.
I wasn't talking about removing it. My point was that if the
optimization fence around CTEs is removed a lot of people will need to
rework apps where they have used them for that purpose. And I continue
to think that spelling it "OFFSET 0" is horribly obscure.
