          # Content type can no longer be cached as public and tenant schemas
          # have different models. If someone wants to change this, the cache
          # needs to be separated between public and shared schemas. If this
          # cache isn't cleared, this can cause permission problems. For example,
          # on public, a particular model has id 14, but on the tenants it has
          # the id 15. if 14 is cached instead of 15, the permissions for the
          # wrong model will be fetched.
