I'm sharing the slides and transcript from my talk about the PostgreSQL Europe Diversity Task Force at PostgreSQL Development Conference 2025.

It's an extended version of the 5 minute lightning talk that I gave at FOSDEM PGDay earlier this year, with some updates on what we've achieved.

If you want a shorter read, feel free to check out the annotated slides from the lightning talk instead!

The new baseline feature in pgroll 0.13.0 makes it easy to start using pgroll on databases with existing schema and keep your schema histories clean.

PostgreSQL versions follow a well-defined five-year support lifecycle. Each major release receives bug fixes, security patches, and minor updates for five years from its initial release date. After that point, the version reaches end-of-life (EOL) and no longer receives official updates.

Even before the Community Summit in Montreal, I wanted to organize a Developers Summit at one of our meetups. My inspiration came from the Open spaces at DevOps Day Chicago. I saw how productive the smaller group discussions could be, and wanted to try to discuss different aspects of interactions.

We finally made it happen on May 22! In the meetup announcement, I asked those signing up to vote for topics we wanted to suggest and name additional topics. Then, when a meetup started, we re-voted the topics, and same as in Montreal, the outcome was different :).

PostgreSQL Person of the Week Interview with Dirk Krautschick: I am Dirk, living near Aachen in Germany and I am actually a Senior Solution Architect with Aiven and a former DBA, Trainer, Consultant and Sales Engineer in several companies but alway related to databases - first Oracle only, later Oracle together with PostgreSQL.

• Postgres Extensions Day took place May 12 in Montreal, Canada, organized by Chris Travers, and Yurii Rashkovskii, with Andrei Lepikhov, Michel Pelletier, and Gwen Shapira additionally on the Talk Selection Committee.

PostgreSQL 18 changes this week

Sadly two features were reverted this week:

planner optimization "Partitions pruned by initial pruning are no longer locked" (commit 525392d5 , reverted in commit 1722d5eb ) function pg_get_process_memory_contexts() (commit 042a6629 , reverted in commit fb844b9f ) PostgreSQL 18 articles UUIDv7 Comes to PostgreSQL 18 (2025-05-09) - Gwen Shapira

more...

So the Beta1 is available for PostgreSQL 18 and while not all the features have to make it to GA, we can surely hope they do!

Taking a close look at what’s coming, here below is the selection of what excites me in particular:

What’s Zig and Zig’s C/C++ compiler?

In case you are not familiar with it, Zig is a programming language. Among other characteristics, Zig prides itself on being a low-level / systems programming language with great interoperability with C and C++.

Introduction

If you’ve created web apps with relational databases and ORMs like Active Record (part of Ruby on Rails), you’ve probably experienced database performance problems after a certain size of data and query volume.

In this post, we’re going to look at a specific type of problematic query pattern that’s somewhat common.

Collation torture test results are finally finished and uploaded for Debian.

The test did not pick up any changes in en_US sort order for either Bullseye or Bookworm

Buster has glibc 2.28 so it shows lots of changes – as expected.

Last week, I presented at the PGConf.dev for the first time and participated in a community summit for the first time. The idea was pitched by Teresa Giacomini, and that’s how this event was described in the program:

Introduction

PostgreSQL Extension Day 2025 made its successful debut on May 12, 2025, just one day before the start of pgconf.dev 2025. This focused one-day event brought together the community around a single theme: the PostgreSQL extension ecosystem. From innovative ideas and development insights to discussions on safer extension building and delivery, the day was all about “everything extensions.”

I gave a presentation at PGConf.dev last week, Adventures in Extension Packaging.

Welcome to the second part of our TimescaleDB best practices series! In the first part, we explored how to perform massive backfill operations efficiently, sharing techniques to optimize performance and avoid common pitfalls. If you haven’t had a chance to read the first part yet, you can check it out using this link

In today’s blog, we will discuss another crucial aspect of time-series data management: massive delete operations.

Got interested recently in speed of pg_dump. Specifically, if, over the years, it has became faster, and if yes, how much. Couple of years ago I was in position where we needed to run pg_dump, and found some inefficiencies, which got later patched. This was around the version 12. So, how does the situation look … Continue reading "pg_dump speed across versions"

Introduction

pgconf.dev 2025 just wrapped up in Montreal, Canada, following its successful debut in Vancouver last year—and once again, it delivered a fantastic mix of deep technical content and strong community social activities.

Version 0.3.1 of the open-source Xata Agent adds support for custom MCP servers and tools, introduces Ollama as a local LLM provider, and includes support for reasoning models O1 and O4-mini.

In what I can't say isn't a tradition at this point, we're in an odd-numbered year so there's news on the pdot front! Get it here!

Just over a week ago, I attended PGConf.DE 2025 in Berlin with the rest of the Data Egret team and gave a talk titled “Data Archiving and Retention in PostgreSQL: Best Practices for Large Datasets.” This post is a written version of my talk for those who couldn’t attend.

Below, you’ll find each slide from the talk — along with what was said.
