PostgreSQL maintenance without superuser

PostgreSQL’s moving in on superusers. As of recent releases—starting way back in v9.6 and maturing through PostgreSQL 18 (coming 2025)—there are now **15+ built-in admin roles**. No need to hand out superuser just to get things done. These roles cover the ops spectrum: monitoring, backups, filesystem access, logical replication, and routine maintenance. Fine-grained control without the keys to the whole kingdom. Less god-mode, more role-based delegation by design!
