BTW, as far as that goes, I think the general recommendation is that
the datadir shouldn't be a mount point, because bad things happen if
you mount or unmount the drive while the postmaster is up. I could
see enforcing that, if we could find a reasonably platform-independent
way to do it.
(Of course, / can't be unmounted, so I wonder exactly what bad thing
happened in that story.)
