OK, here you go. Even if archive_mode = always has been introduced in
9.5, but non-exclusive mode is a 9.6 feature, so here are patches down
to this version. I am pretty satisfied by this, and I included all the
comments and error message corrections reviewed up to now. I noticed
some incorrect comments, doc typos and an incorrect indentation as
well for the WARNING reported to the user when waiting for the
archiving.
