Our database consultant was surprised this wasn't already a thing for our database and found this issue. They said this is a pretty standard tool for database tuning. As a leader in managed Postgres, it seems like this would be a win to bring Heroku to parity with other vendors like CrunchyBridge, AWS, Azure, GCP.

We are looking to offer this as part of the future Heroku database offering on the new infrastructure. At this time, we have made adjustments to our shared_buffers and work_mem default values: https://devcenter.heroku.com/changelog-items/2796 We want to deliver great performance for as many of our customers. If the adjustments we made is not meeting your requirement, please let us know.
