Yeah, sorry, I probably should have mentioned that. The structure
needs to be fixed size for us to store it in shared memory.

I think that would be a good idea. And I'd also propose getting rid
of bgw_sighup and bgw_sigterm in both branches, while we're at it.
AFAICT, they don't add any functionality, and they're basically
unusable for dynamically started background workers. Probably better
not to get people to used to using them.
