postgres: upgrade a user to be a superuser?

Question

In postgres, how do I change an existing user to be a superuser? I don\'t want to delete the existing user, for various reasons.

# alter user myuser ...?
         


        

Answer 1

To expand on the above and make a quick reference:

• To make a user a SuperUser: ALTER USER username WITH SUPERUSER;
• To make a user no longer a SuperUser: ALTER USER username WITH NOSUPERUSER;
• To just allow the user to create a database: ALTER USER username CREATEDB;

You can also use CREATEROLE and CREATEUSER to allow a user privileges without making them a superuser.
