Thanks for the PR, @fhueske and @twalthr . I tried to rebase my rowtime
join codes on this branch, but encountered this exception. The test SQL is
`SELECT * FROM OrderA, OrderB WHERE OrderA.productA = OrderB.productB AND
OrderB.rtB BETWEEN OrderA.rtA AND OrderA.rtA + INTERVAL '2' SECOND`. What
should I do to *cast all other fields to TIMESTAMP*.
