If you mean to say that postgresql should use just 8 MB of RAM rather than
running it on a 8MB machine, then that is impossible given how much postgresql
relies upon OS cache.

You may configure postgresql with 8MB shared memory or the old holy default of
512K, but if your database is 100MB and OS is caching half of it on behalf of
postgresql, your goal is already missed..
