Hangfire: Too many connections opened on postgres

Question

I'm trying to set up Hangfire (version 1.7.3) on a C# API with Postgres, but I need to limit the number of connections Hangfire uses in Postgres.

app.UseHangfireServer(config => {
    config.UseServer(2); //that option does't exist for postgres
});

Answer 1

Found proper solution:

var options = new BackgroundJobServerOptions { WorkerCount = 2 };
app.UseHangfireServer(options);

Connections dropped to 6 from 20+ (crash on heroku).
