The Swiss PostgreSQL Conference<\/a> (Swiss PGDay) returned for its 9th edition this year, taking place on June 25 and 26, 2026<\/strong>. Hosted once again at OST Eastern Switzerland University of Applied Sciences in Rapperswil<\/strong> near Zurich, the event brought together members of the PostgreSQL community from across Switzerland and beyond. With two parallel tracks in English and German, the conference was sold out and reflected the continued interest in open-source database technologies among developers, administrators, and businesses.<\/div>\n

\n

As a long-standing supporter of the community, credativ<\/strong> participated as an official sponsor. We were pleased to be on-site to meet users, exchange ideas, share our expertise, and contribute to discussions around PostgreSQL and its ongoing development.<\/p>\n<\/div>\n

Technical Contributions by credativ<\/h2>\n
\n

We were pleased to contribute to this year’s conference with a keynote and a technical talk. We were especially proud that our colleague Josef Machytka delivered the opening keynote to a full auditorium.<\/p>\n<\/div>\n

<\/div>\n

Josef Machytka – Opening Keynote: “The Next Generation Story of PostgreSQL: From Systems Mechanics to Experience Builders”<\/h4>\n
In his keynote, Josef outlined the evolution of PostgreSQL as a historical journey. He started with the early origins of computer science and basic programming paradigms and then covered the contributors who helped develop Postgres into a system suitable for enterprise and production use.<\/div>\n
<\/div>\n
\n

Josef\u2019s talk included a more personal element through the involvement of his wife, Katerina Machytkova, who contributed hand-drawn portraits of the historical figures and contributors referenced in the presentation. The slides accompanied the narrative through the different historical phases discussed in the keynote. The presentation combined technical aspects of PostgreSQL\u2019s development with visual and creative elements in the slides.<\/p>\n

Michael Banck – “Optimizer Hints in PostgreSQL”<\/span><\/h4>\n<\/div>\n

Later in the track sessions, our colleague Michael Banck spoke about optimizer hints, a topic that is often discussed in the PostgreSQL community. Unlike some other relational database systems such as Oracle, SQL Server, or MySQL, PostgreSQL does not traditionally expose direct optimizer hints to users. The general approach in core development has been to treat optimizer-related issues as something to be addressed in the planner itself rather than through user-facing hints, which can be difficult to apply in practice in production systems. Michael provided an overview of the different ways the PostgreSQL optimizer can be influenced. This includes adjusting global or session-level configuration parameters as well as using the external pg_hint_plan<\/code> extension. He also discussed ongoing work related to PostgreSQL 19, which is expected to introduce new mechanisms for influencing query planning. In particular, he referred to a patch authored by Robert Haas that introduces pg_plan_advice<\/code><\/a> and pg_stash_advice<\/code>. The goal of this approach is to provide a structured way to pass planning-related input to the system without embedding directives directly into SQL statements. Michael illustrated how both the existing pg_hint_plan<\/code> extension and the upcoming mechanisms could be used to influence query execution plans in complex environments.<\/p>\n

Community Exchange and a Fresh Format<\/h3>\n
\n

During the conference, we had many conversations at our booth with attendees. We would like to thank everyone who took the time to stop by and talk with us. The direct exchange with participants was valuable for gathering feedback on our PostgreSQL consulting and enterprise support work. A networking evening at the end of the first day provided an opportunity for informal exchange in a relaxed setting. The overall atmosphere was friendly and open, which many participants highlighted during the conference. Beyond our own sessions, Swiss PGDay 2026 introduced a new Birds of a Feather<\/strong> (BoF) discussion format alongside poster sessions and Lightning Talks. The format provided additional space for informal exchange on practical topics and production-related challenges that are not always covered in traditional presentations.<\/p>\n

Looking Ahead<\/span><\/h3>\n

Following the event in Rapperswil, we are continuing our plans for the rest of the year. We are preparing our participation in PGDay Lowlands 2026<\/strong> in Utrecht this September, followed by PGConf.EU<\/strong> in Valencia in October.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
