```sql SET optimizer = on; SET optimizer_enable_multiple_distinct_aggs = on; EXPLAIN SELECT a, count(DISTINCT b) AS cnt_b, count(DISTINCT c) AS cnt_c FROM mdqa_part WHERE b BETWEEN 0 AND 2 GROUP BY a; Note: optimizer_enable_multiple_distinct_aggs is off by default; without it ORCA falls back before reaching the buggy code path.
