OK, that's a clear explanation.
I don't know if devs on this forum are server devs too. I would suggest that irrespective of the presence of a server trusted cert (root.crt) that the server be usable by the client, as his any time choice, for encryption only and/or server/client authentication. Other RDBMS allow that : Oracle, Apache Derby and MySQL. Although traffic encryption only raises security concerns, it may be helpful in some limited cases.
Thank you for replying.
