repmgr is an open-source suite of tools (a CLI plus the repmgrd daemon) for managing replication and failover in PostgreSQL server clusters. It automates standby setup, replication monitoring, and manual or automatic failover/switchover operations as a PostgreSQL extension.

Use cases

• set up PostgreSQL streaming replication standby servers
• automate automatic failover when the primary goes down
• perform planned switchover between primary and standby
• monitor replication health across a PostgreSQL cluster
• clone a new standby from an existing node
• promote a standby to primary and reattach other standbys
• send event notifications on replication cluster changes

When to choose

• you run a PostgreSQL cluster and need high availability with automatic failover
• you want a mature, EDB-maintained tool tightly integrated with PostgreSQL's built-in replication
• you need manual switchover for maintenance windows
• you want event notifications and monitoring of replication lag

When to avoid

• you use a database other than PostgreSQL
• you need multi-master or logical replication management
• you prefer a fully managed cloud HA solution like RDS or Cloud SQL
• you need quorum-based consensus failover with external witness-only setups unsupported by your topology
