## What it is
pg_auto_failover is a PostgreSQL extension and service that monitors and manages automated failover for Postgres clusters, providing high availability with a state-machine-based monitor and keeper service. It supports architectures from a simple primary-secondary pair to multiple standbys and Citus clusters.

## Use cases
- automate failover for a postgres primary-secondary setup
- set up high availability for postgresql with two nodes
- manage multiple postgres standbys with synchronous replication
- run a postgres HA monitor service
- implement high availability for a citus cluster
- perform safe switchover and failover without data loss

## When to avoid
- you use a managed Postgres service that already provides HA
- you need multi-master or active-active replication
- you prefer orchestrating failover via Kubernetes operators or Patroni

## Facets
- artifact type: service
- maturity: active
- function: database, monitoring, alerting, deployment
- domain: databases, self-hosted, microservices
- platform: self-hosted
- tags: postgresql, high-availability, failover, replication, postgres-extension, citus, devops, linux, macos, docker
