I'm not sure. But it sounds like it'd possibly slow adoption of the minor releases if we said "hey, make sure that you nowhere set client_min_messages > ERROR", even if it's not particularly meaningful thing to do, as it'd still imply a fair bit of work for bigger applications with not great standards. > And if there is, wouldn't we be breaking it anyway thanks to the > behavioral change? Yea, possibly. I'd assume that it'd mostly have been set out of a mistake, and never really noticed, because it's hard to notice the consequences when things are ok. Greetings, Andres Freund
