  </H2
><P
>   <TT
CLASS="COMMAND"
>initdb</TT
> creates a new
   <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
> database cluster.  A database
   cluster is a collection of databases that are managed by a single
   server instance.
  </P
><P
>   Creating a database cluster consists of creating the directories in
   which the database data will live, generating the shared catalog
   tables (tables that belong to the whole cluster rather than to any
   particular database), and creating the <TT
CLASS="LITERAL"
>template1</TT
>
   and <TT
CLASS="LITERAL"
>postgres</TT
> databases. When you later create a 
   new database, everything in the <TT
CLASS="LITERAL"
>template1</TT
> database is 
   copied.  (Therefore, anything installed in <TT
CLASS="LITERAL"
>template1</TT
>
   is automatically copied into each database created later.)
   The <TT
CLASS="LITERAL"
>postgres</TT
> database is a default database meant
   for use by users, utilities and third party applications.
  </P
><P
>   Although <TT
CLASS="COMMAND"
>initdb</TT
> will attempt to create the
   specified data directory, it might not have permission if the parent
   directory of the desired data directory is root-owned. To initialize
   in such a setup, create an empty data directory as root, then use
   <TT
CLASS="COMMAND"
>chown</TT
> to assign ownership of that directory to the
   database user account, then <TT
CLASS="COMMAND"
>su</TT
> to become the
   database user to run <TT
CLASS="COMMAND"
>initdb</TT
>.
  </P
><P
>   <TT
CLASS="COMMAND"
>initdb</TT
> must be run as the user that will own the
   server process, because the server needs to have access to the
   files and directories that <TT
CLASS="COMMAND"
>initdb</TT
> creates.
   Since the server cannot be run as root, you must not run
   <TT
CLASS="COMMAND"
>initdb</TT
> as root either.  (It will in fact refuse
   to do so.)
  </P
><P
>   <TT
CLASS="COMMAND"
>initdb</TT
> initializes the database cluster's default
   locale and character set encoding. The collation order
   (<TT
CLASS="LITERAL"
>LC_COLLATE</TT
>) and character set classes
   (<TT
CLASS="LITERAL"
>LC_CTYPE</TT
>, e.g. upper, lower, digit) are fixed for all
   databases and cannot be changed. Collation orders other than
   <TT
CLASS="LITERAL"
>C</TT
> or <TT
CLASS="LITERAL"
>POSIX</TT
> also have a performance penalty.
   For these reasons it is important to choose the right locale when
   running <TT
CLASS="COMMAND"
>initdb</TT
>. The remaining locale categories
   can be changed later when the server is started. All server locale
   values (<TT
CLASS="LITERAL"
>lc_*</TT
>) can be displayed via <TT
CLASS="COMMAND"
>SHOW ALL</TT
>.
   More details can be found in <A
HREF="locale.html"
>Section 22.1</A
>.
  </P
><P
>   The character set encoding can be set separately for a database when
   it is created. <TT
CLASS="COMMAND"
>initdb</TT
> determines the encoding for
   the <TT
CLASS="LITERAL"
>template1</TT
> database, which will serve as the
   default for all other databases. To alter the default encoding use
   the <TT
CLASS="OPTION"
>--encoding</TT
> option. More details can be found in
   <A
HREF="multibyte.html"
>Section 22.2</A
>.
