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.) regards, tom lane
