Give all the permissions to a user on a DB

Question

I would like to give an user all the permissions on a database without making it an admin. The reason why I want to do that is that at the moment DEV and PROD are different

Answer 1

I did the following to add a role 'eSumit' on PostgreSQL 9.4.15 database and provide all permission to this role :

CREATE ROLE eSumit;

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO eSumit;

GRANT ALL PRIVILEGES ON DATABASE "postgres" to eSumit;

ALTER USER eSumit WITH SUPERUSER;

Also checked the pg_table enteries via :

select * from pg_roles;
