I'm not clear on what exactly you envision, but if a process needs access to shared buffers, it sounds like it should be a bgworker. I don't quite understand why that process also wants a libpq connection, but that's certainly doable. > But it is not all the cases where we want background workers being tied > with postmaster's duration. Not wanting a process to be tied to postmaster's duration is a strong indication that it better not be a bgworker, I think. Regards Markus Wanner
