In the past, the rewriter could generate a re-written query with a modifying
CTE does not have hasModifyingCTE flag set and this bug cause the regression
test(force_parallel_mode=regress) failure when enable parallel select for
insert, so , we had a workaround 0006.patch for it. But now, the bug has been
fixed in commit 362e2d and we don't need the workaround patch anymore.
Attach new version patch set which remove the workaround patch.
