Description: CREATE DATABASE permission is not inherited.
Details:

Apparently one needs to do a 'set role' in order to gain access to a 'create
database' privilege, even though inherit is set to "true" for the user.

This is contrary to the documentation - which implies that ineritance is
automatic.

Access privileges (granted with GRANT) seem to flow down correctly.

This could be a documentation issue...
