Description
Call createWithNullability on an UnknownSqlType currently returns a NULL type. Furthermore, it's impossible to cast to unknown types, according to SqlTypeUtil.canCastFrom. This introduces a new SqlTypeName – UNKNOWN – which behaves like NULL in all ways except that it's no longer actually equal to NULL, and can always be cast to.
