If you mean something like
prepare foo(int) as with x as (delete from tab where id = $1 returning *) insert into log_table select * from x;
I don't see that the parameter makes things any less well-defined.
If you mean a parameter in the sense of an executor parameter passed
in from a surrounding nestloop, that'd scare me too --- but I thought
we were going to disallow wCTEs except at the top level of a query,
so the case wouldn't arise.
