Hi Guys,
I was wondering what is being done for case-insensitive comparisons.
Also wanted to propose an implementation option, which would be to
allow indexes to be created on UPPER or LOWER. As long as I had an
index on UPPER or LOWER, I could do this efficiently:
WHERE UPPER(T1.lastname) = UPPER(T2.lastname)
Is that a totally crazy suggestion, to allow indexes to be created on
UPPER and LOWER? Maybe this is easy to implement.

Proper internationalization would require indices based on a Collator as
defined by java.text.Collator. In general the default Collator for a
locale is a better basis for sorting than either upper or lower case.
