I don't see any difference in maintenance effort. No matter if the database is self-hosted or in the cloud, I need external backups (built-in backups on that cloud service are convenient but not sufficient) and a tested way to restore the whole infrastructure from scratch. Someone else managing that DB doesn't prevent me (or someone malicious) from destroying the data, various infra screwups still are a thing (though perhaps less common). The only difference is if doing the same things through the managed DB admin panel takes meaningfully less effort than ssh on a self-hosted box; and it seems a wash - in the managed DB is easier to use complicated features than when self-hosted, but they tend to be more complex for simple things.
