Yes, I object. This would completely cripple the performance of some uses of logical messages - a slowdown of several orders of magnitude. It's not clear to me that flushing would be the right behaviour if it weren't released, but it certainly doesn't seem right to make such a change in a minor release. Greetings, Andres Freund
