Thomas Munro fc34b0d9de Introduce a maintenance_io_concurrency setting. ... Introduce a GUC and a tablespace option to control I/O prefetching, much like effective_io_concurrency, but for work that is done on behalf of many client sessions. Use the new setting in heapam.c instead of the hard-coded formula effective_io_concurrency + 10 introduced by commit 558a9165e0. Go with a default value of 10 for now, because it's a round number pretty close to the value used for that existing case.
