Using the infrastructure provided by this patch, it's possible either to wait for the startup of a dynamically-registered background worker, or to poll the status of such a worker without waiting. In either case, the current PID of the worker process can also be obtained. As usual, worker_spi is updated to demonstrate the new functionality. Patch by me. Review by Andres Freund.
