So you want Postgres to be a cheaper Oracle. Hmm. Maybe it will work,
but as Marco Colombo says, you are not going to see Postgres shining by
using that simplistic approach. If you want that, maybe you should look
closely to see where you can find the rusty corner that needs to be
polished.

If you do things as simple as "select count(*) from table", then you
will have to be careful to be really fair in your comparison; you could
misleadingly find that Postgres is much slower on that query.
