Hangfire with PostgreSQL driver.

Hangfire with few plugins can be an absolute godsent in 99% of situations i've encountered. The one downside is the documentation is very very lacking, and you have to google a lot until you get to a good place. Despite that, i've used, use, and will continue to use Hangfire, as it's a great tool!

It’s a simple query to write. You don’t need a library or framework.

Updlock rowlock readpast should do the trick
