Simply create a functional index:
CREATE INDEX foo ON employees (UPPER(firstname));
However, I have just tried this, and it doesn't work for some reason. Anybody?
Cheers...

Related to this, is there any way to make an index for a table
case-insensitive? If you have an index, but use upper() in the select,
the index is not used.
