postgresql bgworker SIGTERM handler called twice

Question

Im using postgresql 10.1 on Mac.

I have a trouble in terminating a background worker using SIGTERM. In my project, im creating a new background worker using RegisterBackgroundWorker(). i have included a test_function, as a signal handler for SIGTERM. No other signal handlers are defined.

pqsignal(SIGTERM, test_function)

when i issue pkill -15 postgres, i see that the handler is being called twice. Why does it happen? Am i missing anything??

You should use PID of the postmaster instead of postgres because this will issue SIGTERM to all the process with that name which will include your BackgroundWorker

kill postmaster-pid

will do it.
