Yes, I think it is (barring a counterexample from someone ... the
UNION rewriter is awfully crufty ...).
It might be nice to allow LIMIT to be attached to subselects rather
than just the top level, but I have no idea what it would take in the
executor to implement that. I could handle fixing the parser & planner
if someone else wants to fix it in the executor.
