Only the Unix superuser can create a database system with a

Specifying a user other than the <productname>Postgres</productname> superuser

Creating a database storage area consists of creating the directories in which

</para> </para>
<para> <para>
There are two kinds of arguments for <application>initlocation</application>. In order to use this command you must be logged in (using 'su', for example)
the database superuser.
First, you can specify an environment variable (e.g. <envar>PGDATA2</envar>).
This environment variable should be known to the backend for later use in
<command>CREATE DATABASE/WITH LOCATION</command>
or
<command>createdb -D <replaceable class="parameter">altdir</replaceable></command>.
However, <emphasis>the backend daemon must have this variable in it's
environment</emphasis> for this to succeed.
Second, you may be able to specify an explicit
absolute path to the top directory of the storage area. However,this second
option is possible only if explicitly enabled during the
<productname>Postgres</productname> installation. It is usually disabled
to alleviate security and data integrity concerns.
</para> </para>
<note>
<para>
<productname>Postgres</productname> will add <filename>/base/</filename>
to the specified path to create the storage area.
</para>
<para>
The backend requires that any argument to <option>WITH LOCATION</option> which is
in all uppercase and which has no path delimiters is an environment variable.
