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..? > pg1 and pg2 are in the same network and are in sync. 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. > I followed official documentation and used the cp command.

I'd strongly suggest you look at proper backup/archiving solutions for PostgreSQL like pgbackrest to use instead. Thanks, Stephen
