Review Comment:
The problem of the `NOT NULL` default is still here since you did not change
the `self.build_schema(columns)`.
This should be the default behaviour:
```rust
pub fn build_schema(&self, columns: Vec<SQLColumnDef>) -> Result<Schema> {
let mut fields = Vec::with_capacity(columns.len());
for column in columns {
let data_type =
self.convert_simple_data_type(&column.data_type)?;
let prevent_null = column
.options
.iter()
.any(|x| x.option == ColumnOption::NotNull);
fields.push(Field::new(
normalize_ident(column.name,
self.options.enable_ident_normalization),
data_type,
!prevent_null,
));
}
Ok(Schema::new(fields))
}
```
then, it would help if you changed the `sqllogictests`, for example, from
```
describe table_with_normalization
----
field1 Int64 NO
field2 Int64 NO
```
to
```
describe table_with_normalization
----
field1 Int64 YES
field2 Int64 YES
```
In this way, you can give the same defaults with PostgreSQL.
