416b8694fa Simplify the way in which the database file is truncated when the last

as truncating a database file is always optional.

90e39ec349 When multiple constraints need to be evaluated for a row, do any constraints 
that involve correlated subqueries last.  Hence, the priority is index-covered
constraints first, correlated subquery constraints last, and all others in
the middle.  This is a
follow-on and improvement to the push-down optimization of check-in [d7bb79ed].
