Running both together at the same time isn't a good way of doing a benchmark though... I would question your intent slightly. Should it be a relative comparison? Or should it be an assessment of what PostgreSQL is capable of and whether that fits a sufficient number of your needs to make it worth adopting? There are many ways to structure a decision as to whether PostgreSQL is suitable for your (business?) needs. Which structure you choose is likely to prejudice your decision, one way or the other. i.e. if capital acquisition costs are the decising factor, then PostgreSQL would always win.
