This vulnerability is present in all supported versions of PostgreSQL for these installers, and possibly exists
in older versions. Both sets of installers have fixed the permissions for these directories for both new and existing
installations. If you have installed PostgreSQL on Windows using other methods, we advise that you check that your
PostgreSQL binary directories are writable only to trusted users and that your data directories are only accessible
