Log message:
    Revise mechanism for getting rid of temp tables at backend shutdown.
    Instead of grovelling through pg_class to find them, make use of the
    handy dandy dependency mechanism: just delete everything that depends
    on our temp schema.  Unlike the pg_class scan, the dependency mechanism
    is smart enough to delete things in an order that doesn't fall foul of
    any dependency restrictions.  Fixes problem reported by David Heggie:
    a temp table with a serial column may cause a backend FATAL exit at
    shutdown time, if it chances to try to delete the temp sequence first.
