Nice!

Although your comment makes me think of the cases where a user has the same table name as the airbyte table in the public schema with a different initialised schema.. That's a real edge case so think we can wait to handle it.

Right, this is possible. But I don't want to deal with such case. User should not touch the initial schema. If they do so, they are asking for trouble themselves.
