Even assuming that you can portably find out how much RAM is going to
kernel cache (which I do not believe), how do you know how much of it
is getting used for Postgres data as opposed to everything else?
At the moment I think that manual handling is sufficient anyway. This
is a relatively low-impact parameter and it doesn't seem too important
to try to get it dead on.
