I think we should change the "check_function_bodies" to something more
general. I like "restore_validation_mode" because it could also be used
to disable foreign key checks which we are discussing. An even more
general idea would be to have something like "restore_mode", and perhaps
could handle cases like allowing a larger sort_mem or other
optimizations during restore.
