Laurenz Albe: Benefits of a DESCending index
© Tobi Albe 2025
PostgreSQL can scan B-tree indexes in both directions. That means that there is little need to create a index in descending order (one created with the DESC clause). However, there are some cases where you need a descending index. There are also some corner cases where a descending index performs better than an ascending one. Follow me to explore use cases for the DESC clause!
Gabriele Bartolini: Postgres in Kubernetes: the commands every DBA should know
For many Postgres DBAs, Kubernetes feels like a new, complex world. But what if your existing skills were the key to unlocking it? This article demystifies cloud-native Postgres by revealing a first handful of kubectl and kubectl cnpg commands that act as your direct translator. I’ll move past the intimidating YAML to focus on the practical, imperative commands you’ll actually use to troubleshoot, inspect, and even perform a production switchover.
Paolo Melchiorre: Install PostgreSQL 18 on Ubuntu 25.10
How-to guide for installing PostgreSQL version 18 on Ubuntu, after a fresh installation of version 25.10 (Questing Quokka).
Paul Ramsey: PostGIS Performance: pg_stat_statements and Postgres tuning
In this series, we talk about the many different ways you can speed up PostGIS. Today let’s talk about looking across the queries with pg_stat_statements and some basic tuning.
Showing Postgres query times with pg_stat_statementsA reasonable question to ask, if you are managing a system with variable performance is: “what queries on my system are running slowly?”
Henrietta Dombrovskaya: Check out my new repo: logs_processing
I finally shared the set of functions that I use to process pgBadger raw output.
There will be more documentation, I promise, but at least the code is there, along with two of many presentations.

Ibrar Ahmed: Scaling Postgres
Postgres has earned its reputation as one of the world's most robust and feature-rich open-source databases. But what happens when your application grows beyond what a single database instance can handle? When your user base explodes from thousands to millions, and your data grows from gigabytes to terabytes?This is where Postgres scaling becomes critical. The good news is that Postgres offers multiple pathways to scale, each with its own advantages and use cases.
Tom Kincaid: Part 2: PostgreSQL’s incredible trip to the top with developers
In August of this year, I published a blog entitled PostgreSQL’s incredible trip to the top with developers which shows how Postgres has become the most used, most loved and most desired database according to the Stack Overflow annual developer survey. In that blog I said, I want to do the series in two parts. After some thought, I have decided to make it a 3 part series. It will break down as follows:

Sergey Solovev: Create and debug PostgreSQL extension using VS Code
In this tutorial we will create PostgreSQL extension ban_sus_query. It will check that DML queries contain predicates, otherwise will just throw an error.
Next, in order not to mislead up, I will use term contrib for PostgreSQL extension, and for extension for PostgreSQL Hacker Helper VS Code extension.

Andrei Lepikhov: Revising the Postgres Multi-master Concept
One of the ongoing challenges in database management systems (DBMS) is maintaining consistent data across multiple instances (nodes) that can independently accept client connections. If one node fails in such a system, the others must continue to operate without interruption - accepting connections and committing transactions without sacrificing consistency. An analogy for a single DBMS instance might be staying operational despite a RAM failure or intermittent access to multiple processor cores.

Mayur B.: PGConf.EU 2025: The Underground Map for Database Nerds
PGConf.EU schedule can feel like a parallel query gone wild, so many great talks but not enough CPU.
I built this guide to help my fellow database nerds skip the overwhelm and enjoy the best prod-DBA focussed sessions without a single deadlock.
Follow this path, and you’ll cruise through the conference like a perfectly tuned autovacuum.
