🇱🇺 Oh right, I almost forgot to share the news... June will be pretty busy 🤯 🤣
I'll be giving a talk at Voxxed Days Luxembourg on June 19!

I'm both excited and a bit nervous. I loved the topic when I submitted it, but now comes the real challenge: writing a talk that actually lives up to it 😅

🎤 "pg_dump ou pas pg_dump, telle est la question"
Because backups aren't just a DBA thing 🙂
