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.
