SERVICE / PostgreSQL HA

PostgreSQL High Availability & DR that can be operated.

Design replication, failover and recovery around explicit failure modes and RPO/RTO objectives, with runbooks and validation that the receiving team can actually use.

Design for failure before it happens.

Replication topology

Choose synchronous/asynchronous behavior, standby roles and network placement according to workload and recovery objectives.

Failover & rejoin

Define promotion, fencing, service redirection, former-primary handling and node rejoin so split-brain risk is controlled.

Backup & restore

Treat physical/logical backup, retention and restore testing as a separate recovery control—not a substitute for replication.

Monitoring & ownership

Track replication lag, WAL, capacity, failed jobs and role state with clear escalation and operating responsibility.

A PostgreSQL HA/DR engagement can include.

✓

Primary/standby architecture

✓

Streaming replication and repmgr

✓

Failover and node-rejoin procedures

✓

Backup and restore validation

✓

Monitoring and alerting

✓

Upgrade and operational runbooks

PostgreSQL HA/DR choices depend on recovery objectives, failure domains, write patterns, network characteristics, backup posture and the team’s ability to operate failover safely.
