Robins Tharakan: Testing PostgreSQL on Debian/Hurd: A Windows + QEMU Adventure

Neues vom PostgreSQL Planet - 14. August 2025 - 16:29
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

Gabriele Bartolini: CNPG Recipe 21 – Finer Control of Postgres Clusters with Liveness Probes

Neues vom PostgreSQL Planet - 14. August 2025 - 16:03

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.

Sergey Solovev: The PostgreSQL Hacker Helper extension is one year old

Neues vom PostgreSQL Planet - 14. August 2025 - 14:09

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.

Jan Wieremjewicz: pg_stat_monitor Needs You! Join the Feedback Phase

Neues vom PostgreSQL Planet - 13. August 2025 - 2:00

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.

Lætitia AVROT: PG Lord of the Ring

Neues vom PostgreSQL Planet - 12. August 2025 - 2:00
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.

Craig Kerstiens: Indexing JSONB in Postgres

Neues vom PostgreSQL Planet - 11. August 2025 - 19:00

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.

Chao Li: HighGo’s Patch to Bring GB18030-2022 to PostgreSQL

Neues vom PostgreSQL Planet - 11. August 2025 - 8:41
PostgreSQL and GB18030-2022 Support

PostgreSQL supports GB18030 as a client-side encoding. A client-side encoding means you can set the encoding from a client application such as psql with:

psql=# set client_encoding to GB18030

This tells the PostgreSQL backend that the client will send SQL statements encoded in GB18030. When the backend receives a statement, it converts the GB18030 byte stream into UTF-8 (the default server-side encoding), and then passes it to exec_simple_query() for execution.

Shayon Mukherjee: Bypass PostgreSQL catalog overhead with direct partition hash calculations

Neues vom PostgreSQL Planet - 10. August 2025 - 4:30
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.

Sarah Conway: Most Desired Database Three Years Running: PostgreSQL's Developer Appeal

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.

semab tariq: Achieving High Availability in PostgreSQL: From 90% to 99.999%

Neues vom PostgreSQL Planet - 8. August 2025 - 15:20

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.
