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.
