Next month, I'll be hosting 2 or 3 discussions of David Rowley's talk, Writing fast C code for a modern CPU (and applying it to PostgreSQL), given at 2025.pgconf.dev (talk description here).

Curiosity often leads to the most interesting technical adventures. This time, I decided to explore something off the beaten path: running Debian GNU/Hurd inside a virtual machine on my Windows 11 host and compiling PostgreSQL from source. This post is part 1 of a multi-part series documenting the process, challenges, and discoveries along the way. Future parts will dive deeper into advanced

In this article, I explore how CloudNativePG 1.27 enhances PostgreSQL liveness probes, including primary isolation checks that mitigate split-brain scenarios and integrate seamlessly with Kubernetes. We also discuss how these improvements lay the groundwork for advanced features like quorum-based failover while maintaining stability, safety, and community-driven decision-making.

PostgreSQL Hacker Helper is a VS Code extension for developing PostgreSQL source code. A couple of days ago (August 9th), one year has passed since the release of version 1.0.0.

Initially, it was a utility for dynamically calculating expressions and casting variables, but after a while I realized that not everything is so simple. The main catch is that there are types (if you can say so) that require special treatment.

At Percona, we believe that great open source software is built with the Community, not just for it. As we plan the next iteration of pg_stat_monitor, our advanced PostgreSQL monitoring extension, we’re taking a closer look at the current feature set and how it aligns with real-world usage. In open source, the community isn’t just a user base, it’s the most important stakeholder. While we set the vision, your feedback is the compass that guides us.

I’ve used PostgreSQL for almost 20 years. During this time, I’ve struggled with its official clients. Normally, I have a good memory (except for people’s names and faces). So having to refer to the tool documentation each time I wanted to use it was very unusual for me. So I asked myself, why is that so? I noticed that there was inconsistency and even incompatibility among flags. Sometimes you need the -d flag for the database name.

Postgres is amazing for many reasons. One area that doesn't get near enough attention is datatypes. Postgres has a rich set of datatypes and one important one for devs to be especially excited about is JSONB.

JSONB which is structured and indexable. In JSON, the B stands for binary (or as we like to think of it B is for better), which means data is pre-parsed as it is stored. How do you get the most out of JSONB from a retrieval perspective? Enter Postgres' rich indexing support.

I subscribe to Medium (don’t judge), and their weekly summary pushed an article to me entitled The Postgres Revolution Is Here: Why Version 18 Changes Everything for Developers. Well, OK, that sounds relevant to my interests. Let’s check it out!

Oh.

Oh, dear.

Oh, sweet Mother of God.

PostgreSQL’s hash partitioning distributes rows across partitions using deterministic hash functions. When you query through the parent table, PostgreSQL must perform catalog lookups to route each query to the correct partition. This results in measurable overhead for high-throughput applications, especially if you decide to use multi-level partitioning schemes where PostgreSQL must traverse deeper catalog structures to identify the target partition. Let’s take a look at some findings on speeding up the part where you already know the partition key values.

PostgreSQL is having more than just a moment—it’s establishing a clear pattern of sustained excellence. For the third consecutive year, this community-driven database has claimed the top spot in the 2025 results for Stack Overflow’s Annual Developer Survey, and the results reveal both what developers value today and where the database landscape is heading.

When you are running mission-critical applications, like online banking, healthcare systems, or global e-commerce platforms, every second of downtime can cost millions and damage your business reputation. That’s why many customers aim for four-nines (99.99%) or five-nines (99.999%) availability for their applications

In this post, we will walk through what those nines really mean and, more importantly, which PostgreSQL cluster setup will get you there.

What do tech journalism, PR, and PostgreSQL have in common? For Elly Phneah, the answer is community. Based in Malmö, Elly is the driving force behind the Malmö Postgres User Group (M‑PUG, for short), where she combines her background in communications with a deep passion for databases and developer communities.
