Does anyone know if Aurora PostgreSQL is a full drop-in replacement for Postgres, or is it "Postgres compatible" but missing some features (like CockroachDB, for example)? I am very interested in this service but some of my projects depend on Postgres-specific features.

Fully Postgres compatible in my experience. As long as you don’t require extensions that AWS doesn’t support. But I believe AWS has the widest array of extensions for Postgres of any cloud provider.
