       <para>
        Specifies the provider to use for the default collation in this

        (if the server was built with ICU support) or <literal>libc</literal>.
        By default, the provider is the same as that of the <xref

      <listitem>
       <para>
        Specifies the collation version string to store with the database.
        Normally, this should be omitted, which will cause the version to be
        computed from the actual version of the database collation as provided
        by the operating system.  This option is intended to be used by
        <command>pg_upgrade</command> for copying the version from an existing
        installation.
