Postgres guys are working on it I believe, but nothing hit the mainline yet afaik.

Not db related but I've switched to it (from epoll + inotify to liburing + inotify) out of curiosity mostly, it's a heck of a lot harder to figure out how to use it, the documentation is mostly reading header comments and author's blog posts.
