Description

For example, there is a following DTO in PostgreSQL:

create table email
(
    account_id varchar(100),
    id varchar(100),
    recipients recipient[],
    subject varchar(100),
    content varchar(100)
);
create type recipient as
(
    email text,
    name  text
);

There is an option to use PostgreSQL array: https://vladmihalcea.com/postgresql-array-java-list/

But there is no option to use in PostgreSQL array custom types.

With Regards

Contributor guide

Research direction
Investigate how Hibernate custom types are registered and how PostgreSQL array support is implemented. Look for existing array type mappings and extend them to handle composite types.
