No problems with that (at least with openssh), even through a firewall:

ssh -l my-secret-key-file -n -N \
    -L 15432:other.host.com:5432 \
    other.host.com </dev/null

psql -h localhost -p 15432 my_database

However,you have to keep in mind that this connection ends up on
other.host.com as a tcp/ip connection on 11.22.33.44, not on 127.0.0.1.
Might need some tweaking in postgresl.conf and pg_hba.conf.
