I thought part of their managed service was that they optimized / tuned your postgres db based on how you were using it. If that is true, then moving off of the managed service means you are tuning postgres yourself now.

Also want to throw in there that it is important to not only compare specs, but to also compare hardware. If DO has newer chips and faster RAM, then you will take a performance hit moving to the new provider even if the machine is beefier.

Pretty certain that DO tunes to broad usage performance optimization (all the easy, obvious performance wins), not dynamically per client to each client's usage.

Here's their pitch: easy setup & maintenance, scaling, daily backups, optional standby nodes & automated failover, fast reliable performance including SSDs, can run on the private network at DO and encrypts data at rest & in transit.

huh, when I used them in the past we had someone specifically look at our RDS and data usage and tune it.

They quote "We’ll handle setting up, backing up, and updating". I interpret that as literally the database itself, not the application specific nature of it—how it's used.

For example, I would be surprised if they noticed that your IOPS was high and you needed to upgrade the storage/disk components. (That would be cool if it's the type of thing they offer).
