PostgreSQL – How to Check if User is Superuser

ByAdmin

The is_superuser configuration setting or attribute determines whether a user has superuser privileges or not. Superusers have the highest level of access and control over a PostgreSQL database cluster, including the ability to perform critical administrative functions.

The is_superuser setting is a boolean attribute associated with database roles (users). When a user is designated as a superuser, their is_superuser attribute is set to true, indicating that they have the highest level of privileges.

To check whether currently logged in user has superuser privileges, you can run the following SQL query:

You can use the below query to check if the user has superuser privileges for any user:

SELECT rolname, rolsuper FROM pg_roles WHERE rolname = 'your_username';

Superuser privileges in PostgreSQL come with a high level of responsibility, and you should exercise caution when assigning these privileges to users. Superusers have the authority to perform potentially destructive actions, so it’s important to limit superuser access to trusted individuals who need these privileges for administrative tasks.
