Ohh, Ohhhhhh, OOOOOOHHHHHH! [waving hand wildly in the air] :)
Because primary key should always be system generated and not a value that
the user ever sees, can modify, or that means anything to anyone other than
the system.
usernames can change. PK's should never change.
In this case, if username is to be unique then it would be considered a
Candidate Key. (Would have been the Primary Key if it were not for the
hanging Chads!) :)
