function field_weight_node_update($node) {

  // Don't need to do anything if no new revision
  if ($node->original->vid !== $node->vid) {
    $field_weights = field_weight_get_node_weight($node->original->vid);

    // ...or if there are no field weights
    if ($field_weights) {

      // And just save it with the new vid
      db_merge('field_weight')
        ->key(array(
        'vid' => $node->vid,
