We have the need to separate user (role) management from infrastructure (database) management.

Granting CREATEROLE to any role also allows this role to create other roles having CREATEDB privileges and therefore
alsogetting CREATEDB privileges.
 

My use case would have been to grant CREATEROLE to any role while still restricting "create database".
