Also encountered a similar case for substr, the return type of `substr` is
utf8view, so if we create a table with utf8view, then the column type will
silently turn into `utf8view`, though we expect it to keep the input column's
type -- utf8
```
create table t as select substr(a, 5, 3) from t1; --t1.a is `uft8`
show columns from t;
datafusion public t substr(Utf8("a"),Int64(5),Int64(3))
Utf8View NO
```
