Consider also the strong likelihood that the data directory's parent
directory is owned by root, so that you do not have the ability to
delete and recreate the data directory because you don't have write
permission on its parent.  The main reason initdb is set up to be able
to start with an existing-but-empty data dir is exactly because creating
that directory may have required permissions that initdb itself hasn't
