Why Does the Root User of My RDS for PostgreSQL Instance Not Have the Super Permissions?

For security, stability, and management purposes, RDS for PostgreSQL does not grant the super permissions to root. The super permissions allow you to perform many critical operations, such as modifying system catalogs and executing system-level commands. These operations may severely impact the operational stability of DB instances and compromise data integrity.

If you need to perform operations that require the super permissions, RDS provides alternative methods. For details about the permissions supported by root, see Privileges of the Root User.
