Re: removal of md5 from example code

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..
