Nothing, your oil pump is driven by the speed of the engine, as long as you are not completely losing pressure and are not lining out the pressure on the other end you are fine.

For example, my Audi S4 runs all the way to 5 bar, or 73 psi, when I floor the throttle, though it idles around 1.5 bar, or 22 psi. As a rule of thumb all you need is about 10 psi of pressure for every 1,000 rpm.
