If you put the same pressure in on a 19mm rim you'd be more likely to pinch flat or hit the rim.
That's just maths.
Don't know the exact pressure it was at, but didn't feel low. Never knew exactly with the narrower rim either and never had such a problem. Just something for people to be aware of, user error is more likely.
