How to write a native query in spring boot jpa(postgres) which has "where in" check on composite columns?
What you are trying to do is not supported in JPA/JPQL or Spring Data (see here) Not even all databases support that syntax as far as I'm aware. You either need to concat the columns or add functionality to do this yourself, perhaps a Hibernate UserType will work.

How do access sql through java in the real world?
If you go with hibernate note that there are a few different ways to use it. It can be used standalone and it can be used as a JPA implementation. If you use Spring and use hibernate as a JPA implementation then a popular Spring data layer abstraction is Spring Data which has JPA support with its Spring Data JPA library (https://spring.io/projects/spring-data-jpa)

Integrate txtai with Postgres
Another key feature of txtai is being able to quickly move from prototyping to production. This article will demonstrate how txtai can integrate with Postgres, a powerful, production-ready and open source object-relational database system. After txtai persists content to Postgres, we'll show it can be directly queried with SQL from any Postgres client

I Deployed My Own Cute Lil’ Private Internet (a.k.a. VPC)
Each app’s front end is built with Qwik and uses Tailwind for styling. The server-side is powered by Qwik City (Qwik’s official meta-framework) and runs on Node.js hosted on a shared Linode VPS. The apps also use PM2 for process management and Caddy as a reverse proxy and SSL provisioner. The data is stored in a PostgreSQL database that also runs on a shared Linode VPS. The apps interact with the database using Drizzle, an Object-Relational Mapper (ORM) for JavaScript. The entire infrastructure for both apps is managed with Terraform using the Terraform Linode provider, which was new to me, but made provisioning and destroying infrastructure really fast and easy (once I learned how it all worked).

Test Driving a Rails API - Part One
A running Rails application needs a database to connect to. You may already have your database of choice installed, but if not, I recommend PostgreSQL, or Postgres for short. On a Mac, probably the easiest way to install it is with Posrgres.app. Another option, the one I prefer, is to use Homebrew. With Homebrew installed, this command will install PostgreSQL version 16 along with libpq:
