-   <command>initdb</command> initializes the database cluster's default
-   locale and character set encoding. Some locale categories are fixed
-   for the lifetime of the cluster. There is also a performance impact
-   in using locales other than <literal>C</> or <literal>POSIX</>.
-   Therefore it is important to make the right choice when running
-   <command>initdb</command>. Other locale categories can be changed
-   later when the server is started. <command>initdb</command> will
-   write those locale settings into the
-   <filename>postgresql.conf</filename> configuration file so they are
-   the default, but they can be changed by editing that file. To set the
-   locale that <command>initdb</command> uses, see the description of
-   the <option>--locale</option> option. The character set encoding can
-   be set separately for each database as it is created.
-   <command>initdb</command> determines the encoding for the
-   <literal>template1</literal> database, which will serve as the
-   default for all other databases. To alter the default encoding use

-   Although <command>initdb</command> will attempt to create the
-   specified data directory, often it won't have permission to do so,
-   since the parent of the desired data directory is often a root-owned
-   directory.  To set up an arrangement like this, create an empty data
-   directory as root, then use <command>chown</command> to hand over
-   ownership of that directory to the database user account, then

+   (<literal>LC_COLLATE</>) and character set classes
+   (<literal>LC_CTYPE</>, e.g. upper, lower, digit) are fixed for all
+   databases and can not be changed. Collation orders other than
+   <literal>C</> or <literal>POSIX</> also have a performance penalty.
+   For these reasons it is important to choose the right locale when
+   running <command>initdb</command>. The remaining locale categories
+   can be changed later when the server is started. All server locale
+   values (<literal>lc_*</>) can be displayed via <command>SHOW ALL</>.
