+This feature allows backends to queue multiple read requests, which allows for more efficient sequential scans, bitmap heap scans, and vacuums.
This is enabled by server variable io_method, with server variables io_combine_limit and io_max_combine_limit added to control it. This also enables
effective_io_concurrency and maintenance_io_concurrency values greater than zero for systems without fadvise() support. The new system view pg_aios shows the file handles being used
for asynchronous I/O.
