Well, this is a *BAD IDEA*. Suppose, for example, your data is corrupt in
some special way, an due to your removal of the pid file, postmaster tries to
recover the database automatically and probably destroys all or data part of
the data. You would like to have been able to do a filseystem level backup
first...
