Pushing down statements to FederatedX engine is implemented by printing either SELECT_LEX or SELECT_LEX_UNIT into a string and sending that string to the engine. In the case of pushing down a single SELECT having a CTE (WITH clause) there was a problem, because normally single SELECTs were printed using SELECT_LEX::print(). But CTEs are stored in the upper unit of the SELECT_LEX - SELECT_LEX_UNIT, so they were not unfolded in the string produced. The solution is to invoke SELECT_LEX_UNIT::print() when pushing down single SELECT statements (but not those which are parts of units), so the possible CTEs are unfolded and printed.
