> The {{CharTypeInfo}} stores the type name of the data type (char/varchar) and
> the length (1-255). {{CharTypeInfo}} objects are often getting cached once
> they are created.
> The {{hashcode()}} and {{equals()}} of its sub-classes varchar and char are
> inconsistent.
> * Make hashcode and equals consistent (and fast)
> * Simplify the {{getQualifiedName}} implementation and reduce the scope to
> protected
> * Other related nits
