<para>The <envar>PGDATA</envar> environment variable is used to distinguish database
clusters from one another by setting it to the value of the directory
which contains the cluster desired. The three configuration files
exist in every <filename class="directory">PGDATA/</filename> directory. 
Details on the format of the files and the options that can be set in 
each can be found in <ulink
