+- Make PostgrestResponse data always an array
+- Introduce PostgrestSingleResponse and make single return PromiseLike<PostgrestSingleResponse<T>>. This means single has to be called at the very end of the method chain in a TypeScript context.
+- Make sure PostgrestResponse is correctly assigned as the return type of onfulfilled callback.
