Sorry to be the grump here: You start several threads a week, often clearly not having done much, if any, prior research. Often even sending the same question to multiple lists. It should not be hard to find an explanation for the behaviour you see here. pgsql-hackers isn't a "do my work for me service". We're hacking on postgres. It's fine to occasionally ask for direction, but you're very clearly exceeding that. Greetings, Andres Freund
