I think what longfemur may have been driving at is that to support more weight adequately to avoid pinch flats, you need more air. Also, to avoid excessive squashing down of the side wall which slows you down. With a narrow tire, the ideal for someone your weight is way up there in psi's. IRC a Bicycle Quarterly article from a year or two ago, it's a good deal higher than 130. With a wider tire the greater volume of air allows you to run somewhat lower psi's.
If they fit your frame and brakes, I think you'd be best off using 28s such as Ruffy Tuffy's (IMO, great flat protection and ride but less fast). However, when this has come up before, lots of weighty people have chimed in about how they've successfully riden 23c race tires for years, and they have, so ultimately it will come down to your preference.
