An unknown event should never occur.
It is never written to a binary log. If an event is read from a binary log that cannot be recognized as something else, it is treated as UNKNOWN_EVENT.
The Post-Header and Body for this event type are empty; it only has the Common-Header.

This event type should never occur.
It is never written to a binary log. If an event is read from a binary log that cannot be recognized as something else, it is treated as Unknown_event.
| buf | Contains the serialized event. |
| fde | An FDE required by Binary_log_event constructor. |
