PGConf India 2026 - Review

This was my first time attending PGConf.India. Something I wanted to do for quite a while, heard good things about the conference. but never had a chance before. The conference is well attended, and very vibrant. Good presentations, a lot of questions about *WarehousePG* (the talk I gave) and about *PostgreSQL* in general.

PostgreSQL Berlin March 2026 Meetup

On 5th of March, 2026, we had the PostgreSQL March Meetup in Berlin. Zalando hosted it again, and like last time it was four regular talks in two parallel tracks. The Meetup took place in the Hedwig-Wachenheim-Straße in Berlin, right around the corner from the Uber Arena and East Side Gallery. The event was co-sponsored by Zalando (venue, drinks) and AWS (pizza, snacks).

The 1600 columns limit in PostgreSQL - how many columns fit into a table

A recent blog posting by Frédéric Delacourt reminded me once again that in the analytics world customers sometimes ask for more than 1600 columns. But is that even possible?

PostgreSQL Hacking Workshop - August 2024

On August 8th and August 15th, the first two 'PostgreSQL Hacking Workshops' took place. Robert Haas previously asked on Discord for topics, and the highest vote was for 'PostgreSQL Optimizer Methodology'. The invited attendees are expected to watch the video before, and bring questions to the workshop.

PgConf.Russia 2016

I had the honor to present at PgConf.Russia 2016. It’s probably the biggest PostgreSQL conference in Europe (News report), even bigger than pgconf.eu. It shows that PostgreSQL, and Open Source in general, has a big and growing market share. Was the first time that I travelled to Russia, and as with almost every new country, it is incredible. Also it is nice to be not in charge for a conference, and to enjoy the time attending talks, discuss with others or get stuff done.


Greenplum Database is Open Source

As promised earlier this year, Pivotal released the code for Greenplum Database into Open Source.

Greenplum Database is based on PostgreSQL (was forked from PG 8.2), and features a massive parallel processing system (MPP) to run SQL queries on very large data sets. The code base is licensed under the Apache 2.0 license, and available on GitHub. You can fork the project from there, or submit patches and new features.
