Add assertion about ssize_t narrowing in AIO code The result from pg_preadv() or pg_pwritev(), which is of type ssize_t, is assigned to PgAioHandle.result, which is of type int. This should be ok because the maximum result is limited by PG_IOV_MAX times BLCKSZ. Add an assertion and a code comment to explain and check this.
