// 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.
