In versions 8.2 and up, the grammar allows attaching ORDER BY, LIMIT,
FOR UPDATE, or WITH to VALUES, and hence to INSERT ... VALUES.  But the
special-case code for VALUES in transformInsertStmt() wasn't expecting any
of those, and just ignored them, leading to unexpected results.  Rather
than complicate the special-case path, just ensure that the presence of any
of those clauses makes us treat the query as if it had a general SELECT.
