“Let's build a homemade billing system”, now you have four problems
Using Temporal is in the category of building it yourselves, not a billing service. But it makes it take much less time to build, because it makes the changes, scaling, and grandfathering quick to do. Especially with the new Scheduled workflows feature: https://github.com/temporalio/samples-typescript/tree/main/s...

Temporal for VS Code
The humanVerificationWorkflow workflow used above is in temporalio/samples-typescript. For a more in-depth demo, see this video.

Scheduled jobs
Temporal is a great way to schedule things. Can do sleep('6 months') in a durable function ("workflow"), or can do Scheduled workflows like this.

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.
