I think this is worth considering but note that we already have a
similar mix in other views like pg_stat_archiver (archived_count and
failed_count are dynamic whereas other columns are static). On the
one hand, it is good if we have a separate view for such dynamic
information but OTOH users need to consult more views for replication
information.
