One of the elements that had to be in place for this whole thing of
multiple configuration files to be allowed was for pg_settings to
include precise information about, for each setting, where is its value
coming from. I doubt any of the systems you mentioned have comparable
functionality. If the admin has trouble figuring it out, he needs only
look into that view.
