How to correctly insert with array type (ex bigint[]) columns?

[iamhook]

In my case, I have a class Product and table product:

@Entity(name = "product")
@Table(schema = "delivery", name = "product")
@Getter
@Setter
public class Product extends BaseEntity<Long> {

    @Column(name = "cost")
    private Double cost;

    @Column(name = "picture")
    private String picture;

    @Column(name = "categories")
    private List<Long> categories;

}

create table product
(
    id         bigserial                              not null
        constraint product_pk
            primary key,
    title      varchar                                not null,
    created    timestamp with time zone default now() not null,
    updated    timestamp with time zone,
    cost       double precision         default 0     not null,
    categories bigint[],
    picture    varchar
);

There is a problem with categories field.

I want to insert Product object to database.
Running

Product product = new Product();

        product.setTitle("Milk");
        product.setCost(100.);
        product.setCategories(Arrays.asList(10l, 20l));

        String query = "insert into delivery.product (title, cost, categories) " +
                "values (:title, :cost, :categories)";

        try (Connection con = sql2o.beginTransaction()) {
            con.createQuery(query)
                    .bind(product)
                    .executeUpdate();

            con.commit();
        }

I get org.sql2o.Sql2oException: Error in executeUpdate, ERROR: INSERT has more expressions than target columns, because the final query looks like insert into delivery.product (title, cost, categories) values (?, ?, ?,?) RETURNING *. One parameter of type List<Long> transformed to two positions in query!

The solution I found is to use

String query = "insert into delivery.product (title, cost, categories) " +
                "values (:title, :cost, :categories)";

        try (Connection con = sql2o.beginTransaction()) {
            Query q = con.createQuery(query)
                    .bind(product);

            Long[] longs = new Long[product.getCategories().size()];
            product.getCategories().toArray(longs);
            try {
                q.addParameter("categories", con.getJdbcConnection().createArrayOf("bigint", longs));
            } catch (SQLException throwables) {
                throwables.printStackTrace();
            }
            q.executeUpdate();

            con.commit();
        }

But it is not good idea, I think.

The main question is: can we make Qyery.bind() work with List/Array parameters when insert?
