Configure a sequence. The flags are only effective when creating a
sequence. Calling <code class="methodname">DbSequence::set_flags()</code> is additive; there is no
way to clear flags.

<p>
The <code class="methodname">DbSequence::set_flags()</code> <span>

exception that encapsulates a non-zero error value on
failure, and returns 0 on success.
