+   To prevent server spoofing from occurring when using
+   <link linkend="auth-password">scram-sha-256</link> password authentication
+   over a network, you should ensure that you connect to the server using SSL
+   and with one of the anti-spoofing methods described in the previous
+   paragraph. Additionally, the SCRAM implementation in
+   <application>libpq</application> cannot protect the entire authentication
+   exchange, but using the <literal>channel_binding=require</literal> connection
+   parameter provides a mitigation against server spoofing. An attacker that
+   uses a rogue server to intercept a SCRAM exchange can use offline analysis to
+   determine the hashed password from the client.
