It would be nice to have a program that could run on any OS postgresql
runs on and could report on the current limits of the kernel, and make
recommendations for changes the admin might want to make.

One could probably make a good stab at effective cache size during
install. Anything reasonably close would probably help.

Report what % of said resources could be consumed by postgresql under
various circumstances...
