Yes if the master is running normally. OTOH, if the master is not running (i.e.,
failover case), the standby cannot receive again the data which it failed to
receive.
I found this issue when I shut down the master. When the master shuts down,
it sends the shutdown checkpoint record, but I found that the standby failed
to receive it.
