$ man postsuper (also at http://www.postfix.org/postsuper.1.html)

       -r queue_id
              Requeue the message with the named queue ID from the named  mail
              queue(s) (default: hold, incoming, active and deferred).

$ man postfix (also at http://www.postfix.org/postfix.1.html)

       flush  Force delivery: attempt to deliver every message in the deferred
              mail queue. Normally, attempts to deliver delayed mail happen at
              regular  intervals,  the  interval  doubling  after  each failed

See the difference? One resubmits mail, the other triggers delivery.
