Here's an easy solution:

psql -c "COPY command here" dbname | ssh user(at)host(dot)net "dd
of=/path/tbl.backup"

You can run this from your local server, and immediately pipe it over
a secure shell to the other server, and write it to a file there.
The /path/ you specify is local to the remote server.
