69f8bb9c72 If a binary operator in a WHERE clause that should be performed with no affinity conversions applied to its operands (see http://www.sqlite.org/datatype3.html) is optimized by index lookup, do not apply any conversions to the key value before looking it up in the index. Fix for 93fb9f89d6.

33e619fc1c Additional refinements to Expr handling. Restore compression of trigger
