Ah, indeed. It fails for me though (Ubuntu 12.04, linux 3.2.0, ext4): $ ln /etc/shadow /tmp/frak ln: failed to create hard link `/tmp/frak' => `/etc/shadow': Operation not permitted but I can see it succeed on older linux. Still $PGDATA with its rwx------ permissions is insulated from any such hard-linking from outsiders, whereas a soft link can point anywhere.
