The final effect of cooking corn dregs in a pressure cooker is different from that of cooking corn dregs in an ordinary pot. The pressure cooker cooks for a shorter time and is more sticky. I have always used a pressure cooker to cook porridge with various grains, and I have never had any problems. The key is to control the size of the fire and turn off the heat to prevent the cooked contents from overflowing and the pressure cooker from deflating.
