Yup.

No, that aspect is not changed in the currently-proposed patch:
we still do parse analysis of all the queries at the beginning.
I'd like to make it work differently eventually, but with feature
freeze so close I do not think that'll happen for v18.
Thinking a bit more about that, if the initial parse analysis succeeds
then the patched code will in fact re-parse before execution if any
DDL changes have occurred. So you get at least some of the desired
behavioral change. But the example given in the docs would still
fail, so I don't feel a need to change the docs yet.
