By default, the database server uses asynchronous I/O on Linux when possible. To use asynchronous I/O, the following conditions must be met:

  1. The library can be loaded at run time.

  2. The kernel has asynchronous I/O support.

If you want to turn off the use of asynchronous I/O, specify the -ua option on the database server command line.
