When using libpq directly, you could use PQsslInUse(),
or PQsslAttribute() for more detailed info. I'm not
sure if ODBC provides any way to get at that.
Or, if you want to check/enforce this from the server side,
you could enable log_connections and see what's logged;
or simply change pg_hba.conf to disallow non-SSL connections.
