+1, but I think your example is not quite right:

> ssh -L 5432:localhost:5432 redhat_ip_address
> pg_dumpall -U postgres | psql -h localhost -U postgres

If you have a local PG server, it's probably using 5432 so that ssh
can't bind to that.  I think you want something like

ssh -L 5433:localhost:5432 redhat_ip_address
pg_dumpall -U postgres | psql -h localhost -p 5433 -U postgres

where "5433" can be any locally-unused port number (caution: untested;
the ssh arguments may still not be quite right).
