Setting Up a Standby Server
Walk through the practical steps to initialize and configure a PostgreSQL standby server for continuous data synchronization.
Welcome to Standby Setup
In this lesson, we'll walk through the practical steps to set up a PostgreSQL standby server. This server will continuously synchronize data from your primary server, acting as a read-replica and a crucial part of your disaster recovery strategy.
We'll cover the necessary configurations on both the primary and the standby.
Primary Prep: Replication User
Before initializing our standby, we need a dedicated user on the primary server with replication privileges. This user will be used by the standby to connect and stream WAL (Write-Ahead Log) data.
Run this SQL command on your primary PostgreSQL server:
CREATE USER repluser REPLICATION LOGIN CONNECTION LIMIT 1 ENCRYPTED PASSWORD 'StrongPassword123!';All lessons in this course
