I received the answer from Kevin Jernigan of Amazon:

A recent change in the Aurora PostgreSQL infrastructure made some internal schemas visible to customers. The “apgcc” schema is used for internal maintenance, and we are happy to drop it for you if it is causing an issue. We will address this in a future release.
