How to create a Super User Account on AWS's RDS Mysql?

Question

The Master user has limited permissions on RDS.

I need SUPER, SYSTEM_VARIABLES_ADMIN or SESSION_VARIABLES_ADMIN privileges, and I don't know how to add them to my user.

Tried this solution from another question:

mysql> GRANT ALL PRIVILEGES ON `%`.* TO 'root'@'14.156.117.179';
ERROR 1410 (42000): You are not allowed to create a user with GRANT

Even trying to give SUPER privilege gives me an error.

ERROR 1045 (28000): Access denied for user 'masteruser'@'%' (using password: YES)

Answer 1

A quote from RDS documentation:

Amazon RDS is a managed service, and it doesn't provide SYS access (SUPER privileges).

So, the answer is that you cannot get SUPER privileges there.
