Tomorrow I will give a presentation about EBR at #DOAG2025 in the Sydney room.
I'm excited because my first-ever presentation abroad, 11 years ago, was at the same conference, in the same room, on the same topic (but a different presentation, and a bit more experienced speaker).

I've just written a SQL query that uses GROUPING SETS and the COLLECT function, and it fails with ORA-3001 (unimplemented feature). I googled it and the first result showed that I had already discovered it 6 years ago 😳
