   Description
  </title>
  <para>
   <application>initlocation</application> 
   creates a new <productname>Postgres</productname> secondary database storage area.
   See the discussion under <xref linkend="SQL-CREATEDATABASE" endterm="SQL-CREATEDATABASE-title">
   about how to manage and use secondary storage areas. If the argument does not contain
   a slash and is not valid as a path, it is assumed to be an environment variable,
   which is referenced. See the examples at the end.
  </para>
  <para>
   In order to use this command you must be logged in (using 'su', for example)
   as the database superuser.
  </para>

   Usage
  </title>
  <para>
   To create a database in an alternate location, using an environment variable:
<programlisting>
$ export PGDATA2=/opt/postgres/data
</programlisting>
Start and stop postmaster so it sees the $PGDATA2 environment variable.
The system must be configured so the postmaster sees $PGDATA2 every time it
starts.
<programlisting>
$ initlocation PGDATA2
$ createdb -D 'PGDATA2' 'testdb' 
</programlisting>
  </para>

  <para>
  Alternatively, if you allow absolute paths you could write:
<programlisting>
$ initlocation /opt/postgres/data
$ createdb -D '/opt/postgres/data/testdb' testdb 
</programlisting>
  </para>
 </refsect1>
</refentry>
