Right -- see the "Frontend/Backend Protocol" chapter in the

http://www.postgresql.org/docs/7.4/static/protocol-flow.html#AEN52782

You can use psql to check if SSL is working. Psql prints a message
like the following if SSL was successfully negotiated:

SSL connection (cipher: DHE-RSA-AES256-SHA, bits: 256)
