There are some cases where I would like to bunch queries into a
transaction purely for speed purposes, but they're not interdependent
for integrity. E.g.,

  BEGIN TRANSACTION;
  UPDATE1;
  UPDATE2;
  UPDATE3;
  COMMIT;

If UPDATE2 fails because it, say, violates a foreign key constraint,
then so be it. I want UPDATE3 to go ahead. Is this not possible, or is
there an option I can use to do these kind of independent-query
transactions?
