The view currently discussed is for *master* servers. We might have some
views for replication activity in *standby* servers. So, I'd like to
choose consistent and symmetric names for them -- for example,
pg_stat_replication_master and pg_stat_replication_standby.
I've expected they will be pg_stat_wal_[senders|receivers]
when I was writing the patch, but any other better names welcome.
However, we have "max_wal_senders" GUC parameter. So, users still
need to know what "wal_senders" is.
