The onFlush event occurs when the EntityManager#flush() operation is invoked, after any changes to managed entities have been determined but before any actual database operations are executed. The event is only raised if there is actually something to do for the underlying UnitOfWork. If nothing needs to be done, the onFlush event is not raised.

The postLoad event occurs for an entity after the entity has been loaded into the current EntityManager from the database or after the refresh operation has been applied to it.
