Summary: Also, inherit `TypedValueException` from `BasicException` instead of `StacktraceException`. This is meant as a basic API change, so that catching query exceptions becomes simpler. The error message can be obtained from `what` method, inherited from `BasicException`. In the future, we may extend the `QueryException`. It could take column/row position in query source, as well as other information. Then provide (or override `what`) a method to format the error message nicely for the user.
