  <para>
   <application>createdb</application> creates a new <productname>PostgreSQL</productname>
   database.
  </para>

  <para>
   Normally, the database user who executes this command becomes the owner of
   the new database.
   However a different owner can be specified via the <option>-O</option>
   option, if the executing user has appropriate privileges.
  </para>

  <para>
   <application>createdb</application> is a wrapper around the
   <acronym>SQL</acronym> command <xref linkend="SQL-CREATEDATABASE"
   endterm="SQL-CREATEDATABASE-title">.
   There is no effective difference between creating databases via
   this utility and via other methods for accessing the server.
