Thanks for the suggestion on using postgres background worker. I tried creating one following the implementation in worker_spi and am able to spawn a background worker successfully.
However, the background worker seems to cause postmaster to crash when I wait for it to finish using `WaitForBackgroundWorkerShutdown. The function called by the background worker is empty except for logging a message to disk. Any ideas on what could be going wrong / tips for debugging? Thanks, Sushrut
