How to get to know the current user account is superuser or not?

Hi All,

I was provided with a user account to access postgresql. I want to process some high-level operations that might need a superuser/admin privileged access. How to get to know the user account I was provided having what kind of privileges? It looks like I don't have super user account! And I want to confirm this at the earliest.

Thanks and Regards,
Siva.
