SSL - Providing client certificates

http://jdbc.postgresql.org/documentation/83/ssl-factory.html states :

"Specifically it would be nice to be able to provide client certificates to be validated by the server."

http://jdbc.postgresql.org/documentation/83/ssl-client.html refers to validating the server's identity only, using javax.net.ssl.trustStore JVM-wide setting.

However, if we set javax.net.ssl.keyStore and javax.net.ssl.keyStorePassword, the SSL connection is established and the client certificate is verified.

This seems contradictory with the documntation, or I am missing something.

I would be happy to read your comments.

Thank you.
