1/2 cup apricot preserves
1/4 cup dark brown sugar
1/4 cup white vinegar
1/2 cup teriyaki or soy sauce
1 teaspoon crushed dry red pepper
1 teaspoon dry mustard

1 1/2 cups water for beef or 2 cups water for pork

Prepare barbecue sauce by mixing together catsup, preserves, brown sugar, vinegar, teriyaki, red pepper, mustard, and pepper. Place roast and barbecue sauce in a large plastic bag and put it in ice box overnight.  put water and cooking rack or steamer basket in a pressure cooker. Cover rack or steamer basket 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. Finely chop onions and add to reduced barbecue sauce. Serve sauce with sliced roast.
