Those who anively follow this suggestion may bump into failure when arhive_mode is on. Thus archive_mode is also worth referred to. But, anyway, IMHO, it is mere a performance tips that is not necessarily required in this section, or even in this documentaiotn. Addtion to that, if we write this for max_wal_senders, archive_mode will deserve the similar tips but I think it is too verbose. In short, I think I would not add that description at all. regards. -- Kyotaro Horiguchi NTT Open Source Software Center
