…zed view (#40658)

## Proposed changes
This is brought by #26146
If create materialized view as following, Should fail, because has the
duplicated column name `o_orderdatE` and `o_orderdate`. But now can
create materialized view successfully. the pr fix this.

```sql
        CREATE MATERIALIZED VIEW mv_1
        BUILD IMMEDIATE REFRESH AUTO ON MANUAL 
        partition by(o_orderdate) 
        DISTRIBUTED BY RANDOM BUCKETS 2 
        PROPERTIES ('replication_num' = '1') 
        AS  
        select o_orderdatE, o_shippriority, o_comment, o_orderdate, 
        sum(o_totalprice) as sum_total, 
        max(o_totalpricE) as max_total, 
        min(o_totalprice) as min_total, 
        count(*) as count_all, 
        bitmap_union(to_bitmap(case when o_shippriority > 1 and o_orderkey IN (1, 3) then o_custkey else null end)) cnt_1, 
        bitmap_union(to_bitmap(case when o_shippriority > 2 and o_orderkey IN (2) then o_custkey else null end)) as cnt_2 
        from (select * from orders) as t1
        group by 
        o_orderdatE, 
        o_shippriority, 
        o_comment,
        o_orderdate;
```
