By default disabled, can be enabled with pgAudit extension



Tools and APIs for analysing and monitoring of Database performance

Web based monitoring tools

Web dashboard, provides Prometheus-compatible metrics endpoints to gather health insights



Replication and Partitioning

By default run on replicaset, can automatically scale based on load
