I would like to do that, but I think we need to at least figure out a
way to provide an escape hatch for people without much shared memory.
We could do that, perhaps, by using a formula like this:
1 CLOG buffer per 128MB of shared_buffers, with a minimum of 8 and a
maximum of 32
I also think it would be a worth a quick test to see how the increase
performs on a system with <32 cores.
