PostgreSQL Automatic Failover: High-Availibility for Postgres, based on Pacemaker and Corosync.

Cloud-native continuous backup for PostgreSQL - WAL/base-backup streaming, compression, encryption, retention, and monitoring in a single binary.

Streaming Postgres logical replication changes atleast-once over websockets

A microservice (sidecar) that helps instantly determine the status of your PostgreSQL hosts including whether they are alive, which one is the master, which ones are replicas, and how far each replica is lagging behind the master.

Stolon is a cloud native database manager and orchestrator for PostgreSQL. It functions as a high availability manager designed to automate failover, replication, and cluster management in distributed environments. The system coordinates synchronous and asynchronous data mirroring and uses a service discovery mechanism to dynamically detect database node addresses. It routes client traffic to the current primary instance through a proxy to maintain application access during role switches. The project covers disaster recovery through point-in-time recovery and the maintenance of multi-site st

Autobase is a self-hosted PostgreSQL database management platform and orchestrator designed to provide database-as-a-service capabilities. It automates the full lifecycle of PostgreSQL clusters, from initial provisioning and deployment to ongoing administration and decommissioning. The system distinguishes itself by treating database infrastructure as code, allowing clusters to be deployed and updated through version control and continuous integration pipelines. It provides both a centralized web console for visual management and programmatic interfaces for automating infrastructure orchestra

Patroni is a high availability manager and cluster orchestrator for PostgreSQL. It functions as a failover controller that monitors database health and manages leader transitions to ensure continuous availability and consistency across multiple nodes. The system relies on a distributed configuration store client to synchronize cluster state and perform leader election. It supports integration with external consensus services such as Etcd, Consul, and ZooKeeper, and provides specific orchestration capabilities for deploying clusters within Kubernetes environments. The project covers the manag
