Hello Postgres folks! We’re happy to announce our next in-person PostgreSQL meetup, which will take place at ULB in **Brussels** 🇧🇪 📅 **When:** Tuesday, **10 March 2026** 📍 **Where:** Université libre de Bruxelles (ULB), Brussels Solbosch campus, same location as FOSDEM, just make sure to find the right building and room 📌 **Room:** S.UA6.124/128 Building U, door A, level 6, room 124 Campus map: https://www.ulb.be/en/solbosch/campus-map Address: Avenue Paul Héger 22, 1050 Brussels This meetup will follow our usual after-work format, with talks, discussions, and plenty of time to catch up with fellow PostgreSQL enthusiasts over food and drinks. **Program** * **18:00** Doors open * **18:20** Welcome by PostgreSQL Users Group Belgium * **18:30** "*MobilityDB: Bringing Mobility Data Inside PostgreSQL*" by Esteban Zimanyi (ULB) * **19:00** "*Scaling Semantic Models: Bespoke PostgreSQL Schemas at SaaS Scale*" by Thijs Lemmens * **19:30** "*Percona Operator for PostgreSQL: An Honest Overview*" by Yoann La Cancellera (Percona) * **20:00** Food & Drinks 🍕 Sponsored by Percona * **21:00** Close A big thanks to **Mahmoud Sakr (ULB)** for hosting and to **Percona** for sponsoring the event 🙏 **More details about the talks:** * **MobilityDB: Bringing Mobility Data Inside PostgreSQL** *MobilityDB is an open source data management and analytics platform for mobility data (https://github.com/MobilityDB/MobilityDB). Its core function is to efficiently store and query mobility tracks such as vehicle GPS trajectories. Built on top of PostgreSQL and PostGIS, it provides spatiotemporal data management via SQL.* *Because it is implemented as a native PostgreSQL extension, MobilityDB can be deployed in traditional on premise setups as well as cloud and edge environments without requiring a separate data platform.* * **Scaling Semantic Models: Bespoke PostgreSQL Schemas at SaaS Scale** *While most CMS platforms rely on generic EAV tables, ContentGrid generates native PostgreSQL schemas directly from user-defined semantic models. We’ll discuss the challenges of automating DDL migrations for thousands of unique schemas and the infrastructure patterns we use to keep this model-driven approach performant, isolated, and manageable at scale.* * **Percona Operator for PostgreSQL: An Honest Overview** *In this talk, we review the Percona Operator for PostgreSQL, how it derives from its Crunchy foundation, how it is architected, and the capabilities it provides. We will examine its strengths and weaknesses, how it approaches vendor lock in, and the strategy shaping the project.* *The goal is not to present a feature list or a how to guide, but to focus on architectural considerations and operational tradeoffs.* We’re looking forward to another great evening of PostgreSQL, community, and good conversations in Brussels. See you there! 🐘💛🖤❤️

# Tired of Endless Swiping? You’re not the only one. Most people who join us say the same thing: **Dating started to feel rushed, performative, and oddly disconnected.** So we built something different. Conscious Connections Club hosts **Relational Labs** — guided social experiences designed to spark real conversation, emotional depth, and authentic connection. Events now run in **40+ cities across six continents**, bringing together singles who value curiosity, presence, and meaningful interaction. Before joining an event, everyone attends a short alignment call so you can understand the space and decide if it feels like your kind of people. ### Get the Zoom Link [\[Here\]](https://www.consciousconnectionsclub.com/join#_ps0z7hzgy) *** # What Happens On The Call This is a **30-minute alignment call with the founder**. On the call you’ll learn: • why this community was created • how Relational Labs are different from speed dating or typical singles events • how we curate intentional spaces across 40+ cities • what actually happens at the events • why many people return again and again Some calls have **a handful of people**, others twenty or more. You’re welcome to simply listen and get a feel for the space. Many people attend their first event **alone** — and most leave having met someone they genuinely want to see again. Sometimes it becomes friendship. Sometimes romance. Often it's simply the relief of realizing **you're not the only one craving deeper connection.** *** ### See If This Is Your Scene [\[Here\]](consciousconnectionsclub.com/join) *** # Why We Require This Call The alignment call helps us keep events **intentional, respectful, and aligned**. It also gives you a real chance to feel confident in the experience being right for you before joining a live event. No pressure. Just clarity. *** ### Get the Zoom Link [\[Here\]](https://www.consciousconnectionsclub.com/join#_ps0z7hzgy)

(We will vote between three possible books. I bring two suggestions and we select a third one from the group. So if there is a book you like to discuss feel free to put it forward.) Don't worry if you cannot finish it in time. Just join us for a coffee or tea and a good conversation. :) Happy reading!

Welcome to our weekly event in the upstairs room of The Sister Café, rue Chair et Pain 3, one block from the Grand Place. Please get there early enough to order your drink at the bar first. Thank you! After introductions we will collect questions from the group participants, choose one by voting then discuss it for an hour. Then most of us stay for drinks and bizarre conversations. Past questions have been wide and not confined to academic philosophy: What is a genuine friend? Is social media turning us into emotional zombies? Do we lose some of the experience of things by defining them? Are we driven by sex? Is loneliness a personal failure? Is morality relative? **Crucially, be kind and respectful and generous** in your disagreements; remember how much you personally enjoy someone else proving you wrong before celebrating your cutting counterexamples.

Welcome to our card games night. We will play on Wednesday from 19h-21h at CHEZWaWa Châtelain, a small restaurant. The address is Rue Américaine 91, 1050 Brussels.

Our group gets a 10% discount on food. We encourage you to have at least a drink, it helps to keep the business running ;) If you like, you can also come a bit earlier for a chat or a snack. We'll be there from 18h30. Katja and Bruno

Window functions have nothing to do with the Windows operating system but provide a “window” to a result set when used in SQL queries. They are powerful, set-based methods to view data in unexpected ways. Window functions provide easy, set-based solutions to solve some common problems: * Using running totals * Performing operations in intervals * Identifying data gaps and islands * Performing aggregates without losing detail Many people are confused by window functions and do not know how to use them properly. This session will explore window functions, how they work, and how to use them. Demonstrations with several examples will solidify how window functions can simplify queries and make them more powerful.

**Google Analytics Alternatives** Is it finally time to make the switch away from Google Analytics? Two-and-a-half years ago Jason Packer asked this question at Columbus Web Analytics Wednesday. Since then: Google’s Universal Analytics has been sunset, we’ve changed our name to Columbus Data & Analytics Wednesday, and Jason has released two editions of his book “Google Analytics Alternatives”. Fresh off the release of the 2nd edition of his book, we thought it was time to re-open this conversation. While people love to complain about it, GA’s market share has remained relatively constant (at least in the United States). Why is that? You won’t find any complaints about GA4 in this talk, but rather an overview of what’s currently available in the market and how to frame your decision-making process. We’ll also be giving out some free copies of Jason’s book! So even if you’ve got a “GA4Lyfe” tattoo (no judgement), there’s free books to go with the free pizza and beer.

**Our March pick is *God of the Woods* by Liz Moore.** **This month’s novel is an award-winning literary mystery that blends family drama with psychological suspense. It explores women’s voices and relationships while delivering an exciting, eerie, and deeply suspenseful story. The book is 576 pages in print or 14 hours and 35 minutes on audiobook.** Early morning, August 1975: a camp counselor discovers an empty bunk. Its occupant, Barbara Van Laar, has gone missing. Barbara isn’t just any thirteen-year-old: she’s the daughter of the family that owns the summer camp and employs most of the region’s residents. And this isn’t the first time a Van Laar child has disappeared. Barbara’s older brother similarly vanished fourteen years ago, never to be found. As a panicked search begins, a thrilling drama unfolds. Chasing down the layered secrets of the Van Laar family and the blue-collar community working in its shadow, Moore’s multi-threaded story invites readers into a rich and gripping dynasty of secrets and second chances. It is Liz Moore’s most ambitious and wide-reaching novel yet.
