As @HeartSaVioR mentioned, this is not a bug. Instead, it's the standard SQL
behavior when there is no explicit column list.
```
postgres=# create table t as select 1 a, 2 b;
SELECT 1
postgres=# select * from t;
a | b
---+---
1 | 2
(1 row)
postgres=# create table s(b int, a int);
CREATE TABLE
postgres=# insert into s (select * from t);
INSERT 0 1
postgres=# select * from s;
b | a
---+---
1 | 2
(1 row)
```
Apache Spark 3.1.1 will start to support the explicit column list in `INSERT
INTO` statement.
- https://issues.apache.org/jira/browse/SPARK-32976
Although Spark 3.1.1 is still RC1 and Iceberg 0.11.0 RC0 is not compatible
with it yet, I believe this issue will be resolved by Spark 3.1.1 and Iceberg
0.11.1 combination soon.
