I've repeatedly seen PGDATA or pg_xlog been put directly on a
mountpoint, which means there well be a non-writable lost+found
directory there. (A case with pg_xlog was also reported as a support
case at credativ.) I'm usually advising against using the top level
directory directly, but it's not uncommon to encounter it.
