Can you suggest some factor/clamp values? Obviously it would be
reasonable to set the max clamp at the max shared_buffers size we would
test in the next step, but I'm not sure I see a need for a minimum - all
the factors I'm thinking of (or any factor above 10) would make us
exceed our current minumum (100) in all cases anyway.

OK, will do.
