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.
