For Node.js, my startup used to use [Graphile Worker](https://github.com/graphile/worker) which utilised the same "SKIP LOCKED" mechanism under the hood.

We ran into some serious issues in high throughput scenarios (~2k jobs/min currently, and ~5k job/min during peak hours) and switched to Redis+BullMQ and have never looked back ever since. Our bottleneck was Postgres performance.

I wonder if SolidQueue runs into similar issues during high load, high throughput scenarios...
