PostgreSQL does not care about the permissions on the backup directory
used, and does not set them to 777. In fact, it sets them to to be
accessible only by the owner, so clearly something else is setting
those permissions for you.

It will copy any permissions *inside* the data directory for you, so
if you see 777 there, it means that you have those permissions
somewhere in your production data directory as well.
