module_function def truncate_all
  # We can delete items from 'leaf' to 'trunk' in association terms
  # by using the TSort API (so Address and Customer, for example, are very early,
  # while 'StripeAttributes', which nothing has an FK into, is very late).
  # This is much faster than truncating with cascade.
  # Though in some cases, it doesn't work, so we need to cascade.

      # The table may not exist, maybe because the type was created in a test
      # and now no longer exists but it still a subclass.
