Securing Postgres with streaming replication | POSETTE: An Event for Postgres 2025

Описание: Video of a conference talk about how to secure your database in Postgres using streaming replication, from the very BASIC to the very ADVANCED. After all, even if your database is small, your data might still be precious. And as your project grows and gets bigger, your Postgres environment will need to be adapted to scale with it.

This talk will give you a beginner’s guide to streaming replication in Postgres and more specifically you will learn about WAL (write-ahead logging), how to prepare for DR, and how to prepare for a large setup with cascading replicas, continuous backup, etc. You’ll also learn about the concepts of RTO and RPO and how to scale your data protection architecture as your application grows.

Why attend this talk? Because the amazing power of streaming replication in PostgreSQL is too under-appreciated.

Based on over two decades of practical experience, you will be guided through some of the pitfalls and get introduced to the full range of Postgres Disaster Resilience techniques.
