    Yeah, I agree.  Looks like a simple change in dbconnect():

    /*
    * Use old password if no new one given (if you didn't have an old
    * one, fine)
    */
    if (!pwparam && oldconn)
    pwparam = PQpass(oldconn);

    to

    /*
    * Use old password (if any) if no new one given and we are
    * reconnecting as same user
    */
    if (!pwparam && oldconn && PQuser(oldconn) && userparam &&
    strcmp(PQuser(oldconn), userparam) == 0)
    pwparam = PQpass(oldconn);
