PostgreSQL 9 Replication & Recovery Concepts

The class explains how to use the built-in replication in PostgreSQL 9, along with the fundamentals to understand how it works. High availability and multi-node scaling architectures are both explained. The course workshop focuses on setting up a pair of PostgreSQL on Linux databases to have the same content, followed by breaking the replication and using them independently.

Course Length: 2 days

Who Should Attend:

Database administrators, systems administrators, or developers with working knowledge of database usage.


Students must have a working knowledge of SQL and know the basics of operating a PostgreSQL server. The “PostgreSQL 9 Database Administration” course is recommended before this one. Using the command line interface to a Linux system and some basic UNIX shell programming experience is needed to complete all of the workshop exercises.

Course Outline:

  • pg_dump and restore options

  • PITR Backup and Recovery

  • Replication Concepts

  • High Availability options

  • Streaming Replication

  • Managing clusters using repmgr

  • Hot Standby

  • Synchronous Replication

  • File based Log Shipping

  • Introduction to Slony & Londiste

  • Connection Pooling

  • Upgrading PostgreSQL

  • Sharding and Scale Out 

Benefits of Attendance:

Upon completion of this course, students will be able to:

  • Create and restore a snapshot backup of a PostgreSQL server

  • Deploy a high-availability standby replica

  • Understand the replication scripting hooks used for customizing behavior

  • Monitor whether a replica is keeping up with the master's traffic

  • Switch to a standby system when the master fails

  • Automate server management using the repmgr tool

  • Determine which queries might be answered from a read-only replica

  • Outline popular architectures for scaling a PostgreSQL server across multiple nodes
