Both things fail for me:

regression=# create user admin with createrole createdb;
CREATE ROLE
regression=# \c - admin
You are now connected to database "regression" as user "admin".
regression=> CREATE USER my_user WITH PASSWORD 'my-user-password';
CREATE ROLE
regression=> CREATE DATABASE my_database WITH OWNER=my_user;
ERROR:  must be able to SET ROLE "my_user"
regression=> CREATE DATABASE my_database;
CREATE DATABASE
regression=> ALTER DATABASE my_database OWNER TO my_user;
ERROR:  must be able to SET ROLE "my_user"

I suggest taking this up with AWS.
