  1. Hi, Vlad,

    Your postings are very helpful.

    I have a few questions in regarding of Hibernate JSON and array data type for PostgreSQL.

    My first question is that your solution is more complicated with others. Taking an array of string, for example, others’ solutions has only one UserType interface implementation class while your solution contains four classes. What are advantages of your approach and what are disadvantages of the other approach?

    My second question is why your solution doesn’t come with using list and map data structures while others have that. It is easy to have a list instead of an array and have a map instead of a customized data type in terms of programming.

    Thanks.
