Attaching the patch that improved the message for bg workers in ProcessInterrupts(). For instance, now it looks like FATAL:  terminating background worker "worker_spi" due to administrator command or FATAL:  terminating background worker "parallel worker" due to administrator command and so on for other bg workers.
I'm also mentioning the 2 previous patches posted in [1]. One of the patch is for using die() instead of handle_sigterm() in test_shm_mq/worker.c and another is for replacing custom SIGTERM handler worker_spi_sigterm() with die() and custom SIGHUP handler worker_spi_sighup() with standard SignalHandlerForConfigReload()
