> A SqlTypeName is a _type constructor_, not a type. It is not a full type until it is
applied to parameters. The type name "row" is not a type until applied to a schema. The type
name "array" takes one parameter - the type of its contents.
> We could use Beam's FieldType, but more likely should have a thin wrapper for Beam SQL
types.
