PGConf.EU 2022 in Berlin took place from October 25-28. I was volunteering, and it was very exciting for me.
In the past, I have been to quite a few PostgreSQL conferences, and I did help a bit here and there. But the tasks I got back then have been very easy, and for my age. Like at the conference in Milan 2019 I was going around and announcing the next talks. It was very cool, but also not very challenging.
