The fields in pg_stat_wal_receiver are named after their respective
fields. Now if you look at the fields from pg_stat_replication, you
have those from the standby:
sent_lsn => Last write-ahead log location sent on this connection
write_lsn => Last write-ahead log location written to disk by this
standby server
flush_lsn => Last write-ahead log location flushed to disk by
this standby server
replay_lsn => Last write-ahead log location replayed into the
database on this standby server

So to keep the brand consistent, reply_time looks like the best choice
as Sawada-san suggests?
