Ah I'm just curious about the $$ cost, I 2 RDS PG instances running on t3.medium, one is 30gb never goes over 10% cpu, the other is ~150gb and never goes over 50% cpu. I also have some dynamo stuff for some session management and wonder if it would be better to just shove it in postgres.

So I read your comment as $28k dynamo to $100 postgresql.
