So that's basically the opposite of the case I was thinking about,
where you create a path for a base backup with permissions strictly
higher than 700, say 755, and the base backup path does not have
enough restrictions. And in your case the permissions are too
restrictive because of the application creating the folder itself but
they should be relaxed if group access is enabled. Actually, that's
something that we may want to do consistently across all branches. If
an application calls pg_basebackup after creating a path, they most
likely change the permissions anyway to allow the postmaster to
start.
