Thanks, it sounds promising! Are the changes in the 16 branch already,
i.e. is it enough to fetch sources for 16-beta2? If
so do I just configure --with-liburing (I'm on linux) and run with
io_method=io_uring? Else, if I use the io_method=worker what is a sensible
amount of worker threads? Should I also set all the flags for direct I/O?
(io_data_direct=on io_wal_direct=on).
