Hm. We have been assuming that the contents of a base backup inherit the permission of the source when using pg_basebackup because this allows users to keep a nodes in a consistent state without deciding which option to use. Do you mean that you would like to enforce the permissions of only the root directory if it exists? Or the root directory with all its contents? The former may be fine. The latter is definitely not. -- Michael
