Viacheslav Sarzhan: Community Docker Images: keeping the operator open without a vendor registry lock-in

PostgreSQL community images address a real gap in how a Kubernetes database operator earns your trust. Running a database operator on Kubernetes means trusting two things: the code, and the container images the operator pulls. The code is on GitHub, easy to inspect, easy to fork. The container images, the registry that hosts them, and the license that governs them all sit with the vendor, and any of those three can change without the source repository changing at all. Starting with Percona O...

Understanding the Game

I used to panic when someone asked me what I thought about an acquisition. I had vague opinions, weakly held, because I didn’t know enough to reason about it. My opinions were about the product and the team. Knowing that most acquisitions fail to deliver their value (and having seen a couple up close) the […]

Agriculture is ready for AI, but its data isn’t

Artificial intelligence is transforming what is possible in agriculture, but industry leaders should be wary of investing in AI without first laying the groundwork.  The use cases are promising, especially for an industry navigating volatile fertilizer costs, unpredictable weather, and margins that leave little room for error. Research shows AI-enabled predictive models can improve crop…

The most recent meeting of ISO/IEC JTC1 SC32 WG3 “Database Languages” took place from the 15th to the 19th of June 2026 in Stockholm. “WG3”, as we call it, works on standardizing the database languages SQL and GQL. In that meeting, a number of proposals that are of interest to SQL and PostgreSQL were accepted, which I want to report about here. The meeting code of this meeting was “BMA”, which is the code for a small airport in Stockholm. All in-person WG3 meetings are named af...

AI RPG Migration Can Compile and Still Break Business Logic

AI-assisted RPG migration tools report high compilation success rates while silently failing on behavioral equivalence — packed decimal truncation, activation group persistence, and cycle logic. The benchmarks show why, and what a real accuracy test looks like. The post AI RPG Migration Can Compile and Still Break Business Logic appeared first on Strumenta.

A search index that's also a valid Parquet file: the storage format behind an object-storage-native retrieval engine

Disclosure: I work on infino, an Apache-2.0 embedded retrieval engine in Rust. This is an internals post about one design decision: the risk of Parquet as our on-disk format. I'd like this sub's read on it, links to the relevant code are inline. Our constraint We are building SQL + full-text (BM25) + vector search over a single copy of data living on a Parquet file in object storage (S3/Azure/local). Two requirements fall out of that (design doc: superfile format): the file has to carry its ...

Having written about the Swiss PGDay in 2024, I need not repeat all I said back then. Nonetheless, I'd like to share my impressions from the Swiss PGDay 2026 with you. Turning on to the Swiss PGDay The Swiss PGDay traditionally takes place on the campus of the University of Applied Sciences at Rapperswil. It is perhaps the most inappropriately named PostgreSQL event I know. Only a strong feeling for tradition can maintain the name “PGDay” for a two-day event with two tracks of talks! The ...

Laurenz Albe: Too many tables are bad for you

© Laurenz Albe 2026 (see here for more background) Recently, I helped a customer investigate database problems. It turned out that these problems could be traced back to too many tables in the database. Since this may come as a surprise to many users, I thought it worth the while to write about it. The problems that the customer observed There were two problems that sounded like they might or might not be related to each other: the Linux out-of-memory (OOM) killer occasionally crashed Postg...
