  This chapter discusses how to set up and run the database server,
  and its interactions with the operating system.
 </p><p>
  The directions in this chapter assume that you are working with
  plain <span class="productname">PostgreSQL</span> without any additional
  infrastructure, for example a copy that you built from source
  according to the directions in the preceding chapters.
  If you are working with a pre-packaged or vendor-supplied
  version of <span class="productname">PostgreSQL</span>, it is likely that
  the packager has made special provisions for installing and starting
  the database server according to your system's conventions.
  Consult the package-level documentation for details.
