That's quite old- I'd strongly recommend that you look at using a newer
version.

If hot_standby isn't enable then you won't be able to connect- which is
entirely fine, but if that's what you want then I'm not sure what the error
is that you're concerned about..?

Ok. Note that having only one replica when you're using syncronous
replication will lead to a situation where, if either node fails, the
database system won't accept writes.

The documentation provides an example of how to use the command, using 'cp'
isn't actually recommended. I'd strongly suggest you look at proper
backup/archiving solutions for PostgreSQL like pgbackrest to use instead.
