vcexpert seems too limited for this task.

I feel like gauss could work, but not as reliable as root.

True, but root is safer for starting/stopping databases.

What about option C, sc? It might have some access too.

Yeah, I wouldn't risk it with anything less than root.

I doubt it. Root is the standard for such operations.

Only the root role can manage database operations.

I believe 'root' is the most powerful role, but I need to double-check if 'sc' can also perform those operations.

I’m a bit confused about 'gauss' and 'vcexpert'—I can't recall if they have the necessary permissions.

I remember practicing a question similar to this, and I think 'sc' was mentioned as a role that could manage the database.

I think the 'root' user should definitely have the permissions to start and stop the database, but I'm not sure about the others.
