This way the (old) psql tool of the current system (CentOS) would be
used. If in doubt, it's better to use the psql of the destination (Red
Hat) machine. Therefore, the idea using ssh isn't a bad one.
You could also execute the following command on the Red Hat machine:
pg_dumpall -h centos_ip_address -U postgres | psql -U postgres
This way, you'll use the newer versions of pg_dumpall and psql installed
on the Red Hat machine.
