Right now, the postmaster will let you set any combination of -B and -N
you please. But it seems obvious that there is some minimum number of
buffers per backend below which things aren't going to work very well.
I wonder whether the postmaster startup code ought to enforce a minimum
ratio, say -B at least twice -N ? I have no idea what an appropriate
limit would be, however. Vadim, do you have any thoughts?
