Payload and RDS Postgres

I am tasked to create an SOP system for my company.

i have decided to use payload as CMS to serve my next js frontend and possibly a mobile app in the future.

Currently my plan is to host the project on Vercel and use RDS as the database.

But during development i have encounter the dreaded connection limit issue with RDS

now i have 2 choices, to move the hosting to aws ec2/ which i dont have alot of experience with

or chose a serverless friendly database provider like Neon, Supabase.

the problem is my employer really want me to use RDS

what option should i look into

thanks
