How to Set Up PostgreSQL Streaming Replication on RHEL 9 — step-by-step RHEL 9 tutorial on Progressive Robot

How to Set Up PostgreSQL Streaming Replication on RHEL 9

PostgreSQL Streaming Replication sends WAL (Write-Ahead Log) records from a primary server to one or more standby servers in near-real-time, keeping standbys continuously synchronised with the primary. This provides high availability (automatic or manual failover when the primary fails), read scaling (queries can be distributed to hot standbys), and geographic redundancy. Unlike logical replication which […]
