Your data should be safe: all operations before CLOSE, including
the database SYNC operation, completed without error.
Berkeley DB returns an ENOENT error upon CLOSE. Ignoring such
errors is against the principles on which Postfix is built.
This is why Postfix logs this, and why it logs this as a non-warning.
