FWIW, I think the proper design would rather be a background worker that does this work. Forcing the user to somehow coordinate starting a permanently running script whenever the database restarts isn't great. There's also some issues around snapshots preventing vacuum (which could be solved, but not nicely). Greetings, Andres Freund
