We're using Heroku's PG, and it comes with a default, almost super-user. I'm wanting to restrict that account for only our production app servers, and have anyone connecting for personal queries to go through an assigned role by employee (that's all setup and working).
Other than polling pg_stat_activity (which isn't 100% accurate depending on timing), is there a good way to audit connections? To detect which roles are being used for connections?
