I'm a long time user of DynamoDB for various reasons. I never had to chance to use Postgres for real world. Now, have a new startup and my data model and access patterns do not seem feasible for Dynamo or other document/nosql DBs at all. I'll be probably using Aurora. Another reason is I want to learn Postgres, because its mostly a safer choice. I'm a Spring Boot/Kotlin person because it is currently the fastest way to production for my startup and idea.<p>What guides, good resources can anyone recommend for someone in my position? Everyone here on HN recommends "Postgres is good enough for you, don't look for adventure" in many posts/comments, so thought that would be a good place to ask.
