Thanks for the explanation, I was missing your point.  Hmm.  On top
of my mind, couldn't we also use a regexp for the pg-role rather than
just a hardcoded keyword here then, so as it would be possible to
allow a mapping to pass for a group of role names?  "all" is just a
pattern to allow everything, at the end.
