Aurora PostgreSQL Support

I work as a database admin in my company. We are migrating some of our Oracle databases to Aurora PostgreSQL. Since this falls under the RDS category I understand that the majority of the admin work will be managed by AWS team itself. But from a business unit perspective, they are looking for support from my team with regards to general BU work and performance and tuning. Can someone shed some light on possible areas which we can support in the RDS Aurora PostgreSQL world?

Thanks in Advance!

Thanks,
Goti
