This would reduce the number of workers to be launched by other applications. Also with max_worker_processes = 2 and restart, the system crashes when the 2nd worker is not launched: 2017-02-07 11:36:39.132 IST  LOG: auto pg_prewarm load : number of buffers actually tried to load 64 2017-02-07 11:36:39.143 IST  LOG: worker process: auto pg_prewarm load (PID 20573) was terminated by signal 11: Segmentation fault I think the document should also mention that an appropriate max_worker_processes should be set else the dump worker will not be launched at all. -- Thank you, Beena Emerson Have a Great Day!
