What's wrong with this statement: 'Ideal fluids always flow from high pressure to low pressure'? Could someone give me an example of where this is not true?

Isn't pressure related to velocity? When there is flow through a constriction isn't the pressure in a constriction lower due to the higher velocity? And on the other side then when it slows again?
