+          If local_hot_standby=true, the expectation is that there will be two
+          instances of the server using the same configuration file.
+          The first one to start will be the "primary" instance.
+          The second one to start will be the "standby" instance.
+          The standby instance will initialize and will try to connect on primary_port
+          and secondary_port and admin_port, but will fail because the
+          primary instance has already taken them.
+          So the standby instance goes into a loop, reading the write
+          ahead log which the primary instance is writing (so the
+          two instances are always in synch), and trying to connect on the
+          ports. If the primary instance goes down for any reason,
+          the ports will become free so the standby instance will
+          succeed in connecting, and will become the primary instance.
+          Thus there is no noticeable downtime if the primary instance goes down.
+          If local_hot_standby=true, then replication_source should be an
+          empty string and wal_mode should not be equal to "none".
