I used this web page to implement hot standby via physical streaming. This command sets up everything for you: pg_basebackup \ --pgdata=$PGDATA \ --dbname=service=basebackup \ --verbose --progress \ --checkpoint=fast \ --write-recovery-conf \ --wal-method=stream \ --create-slot --slot=pgstandby1 \ --compress=server-zstd I got it from https://www.tecmint.com/configure-postgresql-streaming-replication-in-centos-8/, which I encourage you to read.
For guarding, and situations with a minimal RTO SLA, I use PgPool-II to manage the cluster, automatic failover and Virtual IP address. Note that only two database servers are needed. Install PgPool on the two DB servers, and a third, smaller system. There are other products which do the same thing as PgPool, and you might find them better.
