The one thing that people seem to forget about is that the DATA does not
have any order at all, so as long as an index is available with a simple
primary key then any record can be found. It's only when you want to
order the data that you need the collation. And then you are creating an
'index' which can be a persistent item, or generated on the fly, but the
raw data will not be affected by that, so sorting case insensitive is no
different to any other sort?
