+      A man-in-the-middle with the ability to inject data into the TCP
+      connection could stuff some cleartext data into the start of a
+      supposedly encryption-protected database session.
+      This could be abused to send faked SQL commands to the server,
+      although that would only work if the server did not demand any
+      authentication data.  (However, a server relying on SSL certificate
+      authentication might well not do so.)

+      This could probably be abused to inject faked responses to the
+      client's first few queries, although other details of libpq's
+      behavior make that harder than it sounds.  A different line of
+      attack is to exfiltrate the client's password, or other sensitive
+      data that might be sent early in the session.  That has been shown
+      to be possible with a server vulnerable to CVE-2021-23214.
