> Still I don't think so correct solution is enabling a unbound SELECTs, but correct is a fix a PERFORM and remove a necessity to use a PERFORM for call of VOID functions.
Well, in this thread, I believe you are the only person who feels that way. And this proposal still would not let PERFORM work with CTEs.
I am thinking, so I propose a enough solution for you - when you use CTE for execution of VOID function, then result vill be VOID set, what we can accept as undefined result, and in this case a PERFORM should not be required. If CTE will return some result, then PERFORM should be required and PERFORM must to support CTE in all possible modes - updateable or not updateable queries.
