SSL connection option from client side?

I got the information about how to set server configuration to make SSL
aware only from http://www.postgresql.org/docs/8.4/static/ssl-tcp.html.
Please see below and let me know if I am missing anything.

1. I need to switch on "ssl" attribute in postgresql.conf and compile the
server again.
2. In pg_hba.conf, I have to use "hostssl" for all client connections.

Also, after setting above configurations, if I connect to my database using
"psql -d Techdb -U postgres" then automatically it will be SSL connection or
I need to specify any option from client side?

Thanks,
Dipti
