Rational approximations of sectional category and Poincar\'e duality
  F\'elix, Halperin, and Lemaire have shown that the rational module category Mcat and the rational Toomer invariant $e_0$ coincide for simply connected Poincar\'e duality complexes. We establish an analogue of this result for the sectional category of a fibration.
