Place roast and barbecue sauce in a large plastic bag, or glass dish.
Place water and cooking rack in a 6-quart Presto pressure cooker.
Cover rack with half of the sliced onions.
Remove roast from sauce (reserve sauce).
Put roast on onions and cover with remaining onions.
Close pressure cooker cover securely.
Place pressure regulator on vent pipe.
Cook at 15 pounds pressure, with regulator rocking slowly, for the following doneness: 8 to 10 minutes per pound for rare; 10 to 12 minutes per pound for medium; at least 12 to 15 minutes per pound for well-done meat.
Cook pork 15 minutes per pound until well done.
Let pressure drop of its own accord.
Meanwhile, place reserved barbecue sauce in a saucepan and simmer, until reduced by about one-half, stirring occasionally.
Remove roast and keep warm.
Discard cooking water or use for making soup.
Purée onions in a blender or food processor and add to reduced barbecue sauce.
