Traditionally yes, but things are changing in this area, if you consider
the top-level file system of a modern Linux distribution.  One reason is
that "run" is/can be blown away at reboot.  This wouldn't be an entirely
useless feature for postgres: Can you tell otherwise which of the
various pid/lock/opts files you can delete if you have killed the
processes and want to eliminate any left-over state?  Is postmaster.opts
a configuration file or a state file?
