Andres Freund c325a7633f aio: Add io_method=io_uring ... Performing AIO using io_uring can be considerably faster than io_method=worker, particularly when lots of small IOs are issued, as a) the context-switch overhead for worker based AIO becomes more significant b) the number of IO workers can become limiting io_uring, however, is linux specific and requires an additional compile-time dependency (liburing). This implementation is fairly simple and there are substantial optimization opportunities. The description of the existing AIO_IO_COMPLETION wait event is updated to make the difference between it and the new AIO_IO_URING_EXECUTION clearer.
