Thanks!
makes it clearer :-)
its not that obvious to guess the consequences of the "volatile" behaviour.

Not sure what you're trying to do with the plpgsql, but you can just
escape the multiple evaluations by putting the volatile

Please don't top-post. Inline (with trim) is better but at minimum

Hi,
your answer helps me understand my first problem.
so, I rewrote a simple loop so as to avoid the "volatile" behaviour.
(at least I was thinking I did... looks like I was wrong !)

DO $$
BEGIN
FOR counter IN 1..1000 LOOP
begin
declare
id1 integer =ceiling(random()*2582);
id3
Ok, thanks for the clarification.
