       <para>
        In contrast to a <function>setval</function> call,
        a <literal>RESTART</literal> operation on a sequence is transactional
        and blocks concurrent transactions from obtaining numbers from the
        same sequence. If that's not the desired mode of
        operation, <function>setval</function> should be used.

       <para>
        The clause <literal>CACHE <replaceable
        class="parameter">cache</replaceable></literal> enables
        sequence numbers to be preallocated and stored in memory for
        faster access. The minimum value is 1 (only one value can be
        generated at a time, i.e., no cache).  If unspecified, the old
        cache value will be maintained.

      <listitem>
       <para>
        This form changes the sequence from unlogged to logged or vice-versa
        (see <xref linkend="sql-createsequence"/>).  It cannot be applied to a
        temporary sequence.

    <term><literal>OWNED BY NONE</literal></term>
    <listitem>
     <para>
      The <literal>OWNED BY</literal> option causes the sequence to be
      associated with a specific table column, such that if that column
      (or its whole table) is dropped, the sequence will be automatically
      dropped as well.  If specified, this association replaces any
      previously specified association for the sequence.  The specified
      table must have the same owner and be in the same schema as the
      sequence.
      Specifying <literal>OWNED BY NONE</literal> removes any existing
      association, making the sequence <quote>free-standing</quote>.
