When evaluating Postgres management services, focus on infrastructure operations and maintenance, disaster recovery, and compatibility, rather than just the feature list. Key validation points include: operational scope (patches, upgrades, tuning permissions), high availability (automatic failover, cross-availability zone switching), backup and recovery (PITR, retention period), compatibility (supported PostgreSQL versions and extensions), migration paths and costs. Red flags include managing only virtual machines, no clear RPO, critical extensions not supported, or data export restrictions.
