One of the biggest problems open source projects face today is the bus factor problem.

I've been thinking a lot about this lately as how it applies to my PostGIS, pgRouting, and OSGeo System Administration (SAC) teams.

 Recently, I attended a conference talk about the vibrant ecosystem of PostgreSQL. It was a fascinating presentation, showcasing the incredible breadth of innovation in the PostgreSQL community. Extensions that push the boundaries of functionality, AI integrations within PostgreSQL, advanced connection pools, and robust cluster management tools were all highlighted.

But something vital was conspicuously absent. Can you guess? That’s right—not a single mention of client connectors.

Postgres Conference Seattle 2024 partnered up with PASS this year to present a united database front. They accepted my “What’s our Vector, Victor?” talk, which I graciously gave on the first day of the conference. If you weren’t there and missed out on the fun, this is your chance to catch up and maybe get a bit more information that was cut for length. Let me tell you why RAG is the future, and how Postgres and pg_vectorize make it a reality.

If you have worked with PostgreSQL for a while, you have probably come across the command VACUUM FULL. At first glance, it might seem like a silver bullet for reclaiming disk space and optimizing tables. After all, who would not want to tidy things up and make their database more efficient, right?

But here is the thing: while VACUUM FULL can be useful in some situations, it is not the hero it might seem. In fact, it can cause more problems than it solves if you are not careful.

PGConf.EU 2024 in Athens is over, time for a review - which is long overdue. With 782 confirmed registrations, it was the largest PostgreSQL conference organized by PostgreSQL Europe - so far. And maybe the largest in-person PostgreSQL community conference world-wide. If you see me writing about “us”, that’s because I’m one of the organizers of this conference. The format was mostly the same as in previous years: Tuesday was training day, provided by sponsors.

Next month, I'l be hosting 2 or 3 discussions of Andres Freund's talk, NUMA vs PostgreSQL, given at PGConf.EU 2024. You can sign up using this form. I anticipate that both Andres and I will be present for the discussions, and I'd like to thank Andres and all of the other presenters who have made time to join the discussions and answer questions for their time (so far: Melanie Plageman, Thomas Munro, Andrey Borodin).

I once wrote about this problem, but given that we now have DO blocks and procedures I can make nicer, easy to use example. Over the years there have been many improvements to how long ALTER TABLE can take. You can now (in some cases) change datatype without rewrite or add default value. Regardless how … Continue reading "How to ALTER tables without breaking application?"

Better later than never – here is a recording of Devrim Gunduz’s talk at the November meetup – enjoy!

This recipe shows how to perform an online major PostgreSQL upgrade using the new declarative approach to logical replication introduced in CloudNativePG 1.25. By leveraging the Publication and Subscription CRDs, users can set up logical replication between PostgreSQL clusters with ease. I will walk you through configuring a PostgreSQL 15 publisher, importing schemas into a PostgreSQL 17 subscriber, and verifying data synchronisation, with the broader goal of highlighting the benefits of a repeatable and testable upgrade process.
