function coder_upgrade_insert_dbtng_statement(&$node, $new) {
  cdp(__FUNCTION__);

  // Create helper objects.
  $editor = PGPEditor::getInstance();

  // Get the function call object.
  $item =& $node->data;

  // Create the expression text to be inserted.
  // TODO Handle the indentation of the output string in the toString() routine.
  $new = implode("\n", $new);

    $comment = '// TODO Please convert this statement to the D7 database API syntax.';
  }
  else {
    $comment = '// TODO Please review the conversion of this statement to the D7 database API syntax.';
  }

  // Insert a comment before the statement containing the function call.
  $item
    ->insertStatementBefore($editor
    ->commentToStatement($comment));

  // Insert a multiline-safe comment with the original function call.
  $string = str_replace(array(
    '/*',
    '*/',
  ), '', $item
    ->toString());
  $item
    ->insertStatementBefore($editor
    ->commentToStatement("/* {$string} */"));

  // Create a new DBTNG expression (of chained operations).
  $temp = $editor
    ->expressionToStatement($new);

  // Insert the expression in the containing statement before the function call.
  $node->container
    ->insertListBefore($node, $temp);

  // Delete the function call.
  // NOTE: This is an example of deleting a function call reference.
  $node->container
    ->delete($node);

  // NOTE: If the replacement was another function call, then we could write:
  //   $temp->parent = $item->parent;
  //   $item = $temp;
