Yeah, we don't want to begin a open battle for that.  Using one column as
a first step would still be useful anyway.  If the discussion about
PQhostaddr() comes to a result at some point, then it could make sense
to integrate that with pg_stat_wal_receiver.  The problem with PQhost
handling strangely multiple host values is inconsistent though.
