PostgreSQL from installation to production: configuration, streaming replication, high availability with Patroni, backups with pgBackRest, performance tuning, extensions, upgrades and migrations from other database engines.
Introduction As PostgreSQL continues to gain traction in enterprise-grade applications, I am increasingly tasked and asked about implementing robust security policies. And, as most current DBA positions are multi-systems nowadays, I wanted to make a quick summary on roles and how they can be leveraged to implement those policies. For those accustomed to managing accounts through Active Directory Security Groups…
As I reflect on my last day at PGConf.EU 2024 in the beautiful city of Athens, I am filled with a profound sense of gratitude and excitement. The conference was a melting pot of innovation, knowledge sharing, and community spirit, all centered around PostgreSQL—a project that continues to inspire and evolve. Here are few of the talks I attended :…
Here’s the following day 2 of the PostgreSQL Conference Europe 2024 in Athens, if you haven’t read the first day here is the link. After a fantastic first day, I was excited to dive into the next day of the conference, which offered a mix of technical sessions that covered essential topics like upgrading PostgreSQL, handling statistics, and even taking…
Attending PostgreSQL Conference Europe 2024 in Athens is an incredible experience, full of enriching conversations and technical deep dives. As a DBA Consultant and speaker (on the reserve list and honored to have been chosen), it was my first time meeting this amazing community in person and I was immediately struck by the camaraderie and shared passion for PostgreSQL. The…
PostgreSQL 17 introduces new features for working with JSON data. These features align PostgreSQL more closely with the SQL/JSON standard and improve the developer experience when dealing with semi-structured data. In this blog, we will explore the new JSON capabilities by walking through real-world examples using a table with a jsonb column. The JSON Data Challenge for Web Developers When…
In database management, query performance is critical for efficient data retrieval. PostgreSQL, a powerful open-source database, offers various extensions to optimize and tune query performance. Two such extensions are Index Advisor and HypoPG. These tools help database administrators (DBAs) identify and test potential indexes to improve query performance without the overhead of creating and dropping indexes repeatedly. This blog will…
Few months ago I write about WiltonDB and how to install it. Now, I move one step forward with the Database Management. How to create a Database ? I test first with the T-SQL Command CREATE DATABASE script: I test now by SSMS GUI: As you can see, only the T-SQL Command script can be used. After the creation, I…
In a distributed database system like PostgreSQL managed by Patroni, etcd plays a critical role as the distributed key-value store for cluster coordination and configuration. As your system evolves, upgrading etcd becomes necessary to leverage new features, bug fixes, and security enhancements. However, upgrading etcd in a live cluster requires careful planning and execution to ensure data integrity. In this…
In PostgreSQL up to version 16, there is no way to evict the buffer cache except by restarting the instance. In Oracle you can do that since ages with “alter system flush buffer cache“, but not in PostgreSQL. This will change when PostgreSQL 17 will be released later this year. Of course, flushing the buffer cache is nothing you’d usually…
Creating REST APIs is a fairly repetitive task. You’re always rewriting the Create, Read, Update, Delete methods…In my search for a framework capable of generating a REST API, I discovered Feathers, a simple and useful framework for Node.js. In this article, we’ll show you how to create a REST API from a PostgreSQL database in just a few minutes. Introduction…
I’m on a mission to tackle scary topics around DevOps these days! In my 2 previous blog posts (Part 1 and Part 2) I’ve tried to demystified the DevOps word (and world!) by describing what it actually is with a simple example. But there is an even scarier topic (true story!), which is… deploying a database in Kubernetes! Database is…
1. Introduction In the world of PostgreSQL database management, ensuring robust backup strategies is mandatory. This week I discovered on postgresql.org latest news one useful tool that streamlines this process: pg_back. pg_back serves as a dedicated dumping tool designed for PostgreSQL. Its primary objective is to facilitate the comprehensive dumping of either all or specific databases, along with global entities,…
