CERN PGDay 2026 took place on Friday, February 6, 2026, at CERN campus in Geneva, Switzerland. This was the second annual PostgreSQL Day at CERN, co-organized by CERN and the Swiss PostgreSQL Users Group. The conference offered a single-track schedule of seven sessions (all in English), followed by an on-site social event for further networking in the inspiring environment of CERN. With around 100 participants, this is already a very large PostgreSQL event for Switzerland. But what made this event absolutely special was its location. Hosting a database conference at CERN – one of the world’s leading science laboratories – provided a unique experience for everyone.
