SR is capability to stream WAL records from the master to the standby and
keep the database on the standby up to date by applying the WAL records.
HS is capability to allow us to run read-only queries on the standby.
You seem to need both SR and HS. So you don't need to change wal_level and
hot_standby parameters.
