I really want BackgroundWorkerHandle to be public, strong +1 from me.

It'd be very beneficial when working with shm_mq, too. Right now you cannot pass a BackgroundWorkerHandle through shmem to another process, either via a static shmem region or via shm_mq. This means you can't supply it to shm_mq_attach and have shm_mq handle lifetime issues for you based on the worker handle.

TBH I think there's a fair bit of work needed in the bgworker infrastructure, but making BackgroundWorkerHandle public is a small and simple start that'd be a big help.

At some point we'll also want to be able to enumerate background workers and get handles for existing workers. Also, let background workers recover from errors without exiting, which means factoring a bunch of stuff out of PostgresMain. But both of those are bigger jobs.
