yes, i know what RETURN does and when it does not exit from function
(like RETURN NEXT or RETURN QUERY), i know that part of docs, even read
that again and again before sending, but i must be blind, because i
cannot see any mention of
<statement> RETURN;
where that RETURN keyword does nothing (note the lack of ; before
return)
maybe knowing all that i just pass the docs too fast, but i honestly
cannot see why is this allowed.

the only similar thing which comes to my mind is a statement with
RETURNING ... clause within cte, but it's not the case here (nor the
same spelling)
