We tried to do this in the Debian package mananger.  It works as
expected on Linux systems, but it can cause a lot of data to hit the
disk, and there are kernel versions where sync(2) never completes if
the system is rather busy.

initdb is much faster with 9.1 than with 8.4.  It's so fast that you
can use it in test suites, instead of reusing an existing cluster.
I think this is a rather desirable property.
