Yes, we could do that but it makes things harder for newbies and really
isn't the right numbers for production use anyway. I think anyone using
default values should see a message asking them to tune it. Can we
throw a message during initdb? Of course, we don't have a running
backend at that point so you would always throw a message.
From postmaster startup, by default, could we try larger amounts of
buffer memory until it fails then back off and allocate that? Seems
like a nice default to me.
