Previously ordered queries on realtime caggs would always lead to full table scan as the query plan would have a sort with the limit on top. With this patch this gets changed so that the ORDER BY and LIMIT can be pushed down so the query can benefit from the ordered append optimization and does not require full table scan. Fixes timescale#4861
