Code

function comment_entity_predelete(EntityInterface $entity) {
  // Entities can have non-numeric IDs, but {comment} and
  // {comment_entity_statistics} tables have integer columns for entity ID, and
  // PostgreSQL throws exceptions if you attempt query conditions with
  // mismatched types. So, we need to verify that the ID is numeric (even for an
  // entity type that has an integer ID, $entity->id() might be a string
  // containing a number), and then cast it to an integer when querying.
  if ($entity instanceof FieldableEntityInterface && is_numeric($entity->id())) {
    $entity_query = \Drupal::entityQuery('comment');
    $entity_query->condition('entity_id', (int) $entity->id());
    $entity_query->condition('entity_type', $entity->getEntityTypeId());
    $cids = $entity_query->execute();
    entity_delete_multiple('comment', $cids);
    \Drupal::service('comment.statistics')->delete($entity);
  }
