Thanks for the reply San Ji :) ActiveModel is database agnostic, however, the `attribute :foo, :my_custom_type, array: true` syntax [from the new activerecord::attributes api]( https://api.rubyonrails.org/classes/ActiveRecord/Attributes/ClassMethods.html) is only available to postgres, [as it's defined on the postgres adapter]( https://api.rubyonrails.org/classes/ActiveRecord/Attributes/ClassMethods.html#method-i-attribute-label-Options )
Possibly my question should be put to the core-team mailing list, as, really I'm wondering about whether the feature should be built in.
