Choose Postgres Queue Technology
To make sure you that the message you are trying to retrieve hasn't been locked already by another worker.

SQL Maxis: Why We Ditched RabbitMQ and Replaced It with a Postgres Queue
SQLite is missing some features like `SELECT FOR UPDATE`, but you can work around some issues with a few extra queries. I wrote litequeue[0] with this specific purpose. I haven't been able to use it a lot, so I don't have real-world numbers of how it scales, but the scaling limits depend on how fast you can insert into the database.

What's New in SQLite 3.35
The `RETURNING` is so awesome! I'm implementing a set of data structures on top of SQLite, one of them is a queue[0], and I had to do a transaction to lock a message and then return it, but this makes it easier.
There's one little issue I keep finding with SQLite, and it's that most virtual servers / VM images ship with version 3.22.0, and upgrading often means building from source.
In any case, SQLite is absolutely wonderful. My favorite way of building products is having a folder for all the DBs that I mount to docker-compose. This release makes it even better.

Choose Postgres Queue Technology
For running queues on Postgres with Node.js backend(s), I highly recommend https://github.com/timgit/pg-boss. I'm sure it has it scale limits. But if you're one of the 90% of the apps that never needs any kind of scale that a modern server can't easily handle then it's fantastic. You get transactional queueing of jobs, and it automatically handles syncing across multiple job processing servers using Postgres locks.

Which tool/library well adopted to use Postgres as a message broker?
I saw this https://github.com/timgit/pg-boss but it's more for jobs than for message with multiple consumers (having their own progress offset).

You don't need distributed systems.
You can use the simplest option than implement a new service. Keep in mind that every running system can be a job scheduler, you can just use nodejs worker threads, Redis, or even your DB as a job scheduler, check PGBoss for example.

Launch HN: Convoy (YC W22) – Open-source cloud-native webhooks service
Both! For context, we're currently using https://github.com/timgit/pg-boss as a task queue on top of postgres and it works great. No need to complicate things with Redis. I believe it's quite straightforward to implement a task queue on top of postgres using the SKIP LOCKED functionality.
