I think it is a classic case of thinking 'small'. :-)
The CIO on the project I'm working on thinks it is a good thing,
but he's coming from a MySQL environment, which he only learned in the
last year or so and he does not appear to have a lot of familiarity with
larger databases.
Personally, if I want case insensitivity, I'll WRITE IT INTO THE CODE,
but I can see how some people might think that 'NOLAN', 'Nolan' and
'nolan' should be considered as the same data.
BTW, I just tested it and MySQL does case folding on values in unique
indexes, too. (Well, at least it is consistent.)
