I think I get it, now. Is the reason for including the `pass` in the example so that the documentation can demonstrate `citext` along side case-sensitive text?
If so, I struggle to come up with anything more obvious than a password hash for a case where case-sensitive comparison of text is necessary. The only other thing that comes to mind is an external system identifier like a Salesforce object id of a user. That would not be as universally obvious an example of case-sensitivity to all PostgreSQL users..
