Description

Currently Schema's addColumn is this

```java
public synchronized Schema addColumn(String name, Type type) {
if (type == Type.CHAR)

{ return addColumn(name, CatalogUtil.newDataTypeWithLen(type, 1)); }

return addColumn(name, CatalogUtil.newSimpleDataType(type));
}
```

I think it is better condition code into CatalogUtil.newSimpleDataType.
because some testcode make columns just using CatalogUtil.
