Exactly - arrays, maps, nested json objects. It's more organized and easier to reason about. As postgresql becomes more and more sophisticated over time, I see flat logging becoming more unwieldy. With tools like jq, reading and querying json on the command line is simple and user friendly, and using json for logging capture and aggregation is widely supporting and embraced.
