### What problem does this PR solve? if mv def sql is as following: ```sql create matrialized view test_mv as select k1, k3, sum(k2), count(k4) from ${tblName} group by k1, k3; ``` if query are as following, should not use test_mv above ```sql select count(k1) from agg_use_key_direct; select sum(k1) from agg_use_key_direct select avg(k1) from agg_use_key_direct ``` the wrong case would happen when in branch-2.1 or `set enable_sync_mv_cost_based_rewrite = false;` on branch-3.0 or master, the pr fix this if query are as following with distinct or is `max` or `min`, can use test_mv above ```sql select count(distinct k1) from agg_use_key_direct; select sum(distinct k1) from agg_use_key_direct select avg(distinct k1) from agg_use_key_direct select max(k1) from agg_use_key_direct select min(k1) from agg_use_key_direct ``` Issue Number: close #xxx Related PR: #xxx Problem Summary: ### Release note Fix use sync mv wrongly when use rbo materialized view rewrite rule ### Check List (For Author) - Test <!-- At least one of them must be included. --> - [x] Regression test - [ ] Unit Test - [ ] Manual test (add detailed scripts or steps below) - [ ] No need to test or manual test.
