[RDS (MySQL)] Super権限操作で出たエラー

Amazon RDSを使用してMySQLを構築し、Super権限が必要な処理を実行しようとした所以下のようなエラーがでました。

ERROR 1227 (42000) at line 8: Access denied; you need (at least one of) the SUPER privilege(s) for this operation

RDSではSuper権限が付与されたユーザはAWS側が管理用に確保しているrdsadminというユーザのみになっており、自身で作成したユーザにはSuper権限が付与されていません(付与することもできません)。

mysql> show grants for 'rdsadmin'@'localhost';
