Hello i try to use PgNotificationHelper (
http://wiki.postgresql.org/wiki/PgNotificationPoller) , the method:

        // not synchronized, must not access pub members
        private boolean poll() {
            assert(status == Status.LISTENING);
            assert(Thread.currentThread().
equals(this));
            try {
                lastPollTimeMs = System.currentTimeMillis();
                helper.poll();
                return true;
            } catch (SQLException e) {
                reportSQLException("Polling for notifications failed, will
try to reconnect", e);
                return false;
            }
        }

method poll in class notify.PgNotificationHelper cannot be applied to given
types required: java.sql.Connection, long, boolean found: no argument.

i know i need to add the parameters, because the parent class have:

public void poll(Connection conn, long pg_backend_pid, boolean
useDummyStatement) throws SQLException {

but, why in PgNotificationHelper don't pass the arguments? is an error?
