There is are no syntax layouts on this page or in similar sections in
the docs --- they are reserved for the reference pages. I don't think
it makes sense to add it here. One odd thing is that WITH can be used
with non-SELECT statements, but we only document it in SELECT, which is
odd. I think that is because the SQL standard only uses WITH with
SELECT.
