Postgres High Availability

Learn how to configure PostgreSQL database instances into a high-availability cluster to increase reliability and resiliency. Compare different options for data replication, switchover, and load balancing in PostgreSQL.

PostgreSQL High Availability HA focuses on minimizing downtime and ensuring continuous service through redundancy replication and automatic failover. Disaster Recovery DR focuses on recovering data and services after a major catastrophic event, often relying on backups stored offsite and potentially involving longer recovery times. HA is

Learn how to set up and use different solutions for high availability, load balancing, and replication in PostgreSQL. Compare synchronous and asynchronous, hot and warm standby, and other options for various workloads and scenarios.

Learn how to achieve high availability for PostgreSQL deployments with different solutions, such as replication, sharding, and failover. Compare the pros and cons of each option and how to measure and optimize uptime based on your RTO and RPO.

Maintaining and monitoring your PostgreSQL HA cluster is crucial for ensuring high availability, data integrity, and optimal performance. The following sections provide some best practices for monitoring and maintaining a PostgreSQL HA cluster.

This guide explores the most common high availability options in PostgreSQL, with explanations, configurations, and examples. Key High Availability Options in PostgreSQL. 1. Streaming Replication. Streaming replication allows a standby server to replicate data from a primary server in real time. It ensures a near-zero recovery point in case of

Learn how to achieve high availability for PostgreSQL databases using replication, failover, load balancing, connection pooling, and other techniques. Explore different deployment models, replication methods, and tools for PostgreSQL high availability.

Setting up a High Availability HA cluster for PostgreSQL typically involves configuring multiple nodes to ensure data availability and reliability. There are various ways to achieve this, in this

High Availability HA in PostgreSQL ensures continuous database operation through replication, automated failover, and robust monitoring. This guide covers everything you need to implement a production-grade HA setup.

PostgreSQL 17 high availability eliminates this risk through streaming replication and automatic failover mechanisms that maintain 99.9 uptime. This guide shows you how to build a production-ready PostgreSQL 17 high availability cluster with streaming replication and pg_auto_failover. You'll configure primary-standby replication, implement
