There is nothing wrong with using mashed potatoes to seal a pinhole leak. It'll work.
Air pressure at sea level is 14.7 pounds per square inch. A pinhole for, say, photography purposes (a *large* pinhole), is 0.0073 inches in diameter, giving it an area of 0.00004185... square inches. Multiply by 14.7 to get the pressure it needs to hold, and you get 0.000615... pounds. So, mashed potatoes has PLENTY of stickiness to hold that measly amount of pressure. I exert a greater difference in air pressure by blowing on my soup.
And that assumed the starship is pressurized to sea level pressure. It's probably not. The space shuttle, for example, only runs at a little more than half that. Space suits for EVAs run at 4.3 lbs of pressure, all oxygen, which is why they require prebreathing.
So, you see, all those years of bad science in scifi movies have steered you wrong. So when something that is actually CORRECT comes along, you get all upset.
All comments made in this post are my opinion and my opinion alone. Deal with it.
