Log message:
    Adjust setRelhassubclassInRelation() to not perform actual heap_update
    when the pg_class.relhassubclass value is already correct.  This should
    avoid most cases of the 'tuple concurrently updated' problem that
    Robert Creager recently complained about.  Also remove a bunch of dead
    code in StoreCatalogInheritance() --- it was still computing the complete
    list of direct and indirect inheritance ancestors, though that list has
    not been needed since we got rid of the pg_ipl catalog.
