Postgres as Queue
Big fan of Graphile Worker to handle this job. https://github.com/graphile/worker
- GitHub - graphile/worker: High performance Node.js/PostgreSQL job queue (also suitable for getting jobs generated by PostgreSQL triggers/functions out into a different work queue)

Choose Postgres Queue Technology
I do enjoy using https://github.com/graphile/worker for my postgresql queuing needs. Very scalable, the next release 0.14 even more so, and easy to use.

PGMQ: Simple Message Queues Built on Postgres
On the same subject (job queue based on PostgreSQL), I'm successfully using the https://github.com/graphile/worker/ (NodeJS) project in production.
Jobs are written in Javascript.

How Trigger.dev makes serverless background jobs possible
Postgres is used both as a store of state for Runs/Tasks and for the Job queue (we use Graphile Worker).

Intro to PostGraphile V5 (Part 2): Plugins and Presets
Having now built V5's unified plugins and presets system, I'm extremely pleased with it! I'm so happy, in fact, that I'm looking forward to integrating it with Graphile's other tools such as Graphile Worker (our Postgres-backed job queue) and Graphile Migrate (a lightweight SQL-based migration framework that focuses on DX) once V5 is out and stable.

SQL Maxis: Why We Ditched RabbitMQ and Replaced It with a Postgres Queue
Another good library for this is Graphile Worker:
https://github.com/graphile/worker
Uses both listen notify and advisory locks so it is using all the right features. And you can enqueue a job from sql and plpgsql triggers. Nice!
Worker is in Node js.

Reactive Backend Applications with Spring Boot, Kotlin and Coroutines (Part 1)
Now that we have an application, let's turn it into a reactive application. For this, we will replace Spring Web dependency with Spring WebFlux, Spring Data JPA with Spring Data R2DBC. We will also add R2DBC dependency for our H2 database. R2DBC works with a reactive driver so it will integrate nicely with the rest of our application to allow us database access in a non-blocking way.

I need to create an API, but I don't know what framework to use. What would you choose, of you were me, and scalability is a quite important factor?
However, if you really expect a lot of users (especially concurrent ones) to use your API, you should delve into the world of reactive programming. Use tools like RxJS (JS/TS) or Project Reactor (Java) in such a case, preferably in combination with a broker like Kafka or RabbitMQ. R2DBC is also great for a data store. Then of course if you want to go one step further, there also exists the less popular but very interesting Actor model which Akka easily has ported into Java.
