Well, I solved adding OPTIONAL to the MATCH, but your solution  
`CREATE OR REPLACE DATABASE gdpr` looks more effective and elegant.

Chapeau!

..... but it cannot be used in a composite database because I have to recreate the DB then recreate all the aliases ....

So, the winning solution to empty a federated DB is

```auto
CALL {
USE federatednotions.gdpr
optional MATCH (n) DETACH DELETE (n)
} 

```
