in Postural hypotension there is less blood flow to the renal arteries- so increased renin secretion..
Due to the increased renin. there is increased AT1 and 2 which increases Aldosterone.
Aldosteron tends to cause hyernatremia and hypokalemia..

How do you think that potassium can be altered by that mechanism, please first refer to a physiology book.
