Throttling with Postgres storage

Anybody using the Hangfire.Ace package with its throttling and rate limiting functions while using Postgres storage?

We are using this package for storage. But I see the Hangfire.Ace package presumably will not work with that.

Or any other options for implementing semaphore type function while using Postgres storage?

@odinserj Is there documentation anywhere on what is required of the storage implementation to work with the Hangfire Concurrency/Rate Limiting package?

I came across this comment but details are sparse.
