I've handled SIGTERM signal. pg_terminate_backend send signals (SIGTERM) to backend processes identified by process ID. And also, after this call I am able to track in my logs that the background worker gets terminated.
Yet, I am only able to register first 8 background workers. I am using select worker_spi1_launch(1) to launch it every time. This is why I guess there is some metadata maintained which has got to be deleted.

Why don't you just register and use a signal in this case? You could even do something with SIGHUP... -- Michael
