There’s two main reasons: First, it doesn’t actually make sense to include RssFile when measuring a postgres backend’s memory usage - for postgres that overwhelmingly just are the postgres binary and the shared libraries it uses (postgres does not mmap() files). If you create a PostgreSQL server and delete it after five minutes, you are charged for one full hour for the provisioned compute and storage.
