I saw from the web interface that maintenance on my RDS postgresql instances is required, so I ran aws rds describe-pending-maintenance-actions, and it says that there's a "system-update" because "New Operating System update is available".

That's fine, so I restarted the instances 90 minutes ago (aws rds stop-db-instance then aws rds start-db-instance).

90+ minutes later, the instances are still "Maintenance Required".

What did I do wrong, or not do? Or is this just a notification that AWS is going to be doing something that's outside of my control?

$ aws rds describe-pending-maintenance-actions --output=table
