Hmm, isn't this strange? open(3) is not documented to return EPERM,
which is what this error string maps to.
You should definitely not mess with the PG data dir; if you do, it's
your problem when things break. In this case you may not be messing
with the data dir yourself, but perhaps you kernel is buggy or you have
some security module that prevents the operation from working properly,
or something.
