Case sensitivity

[Dario Ottaviano]

I use postgres on a window server (IIS 5.1)
Is there anybody that knows if is possible to make postgres no case
sensitive in the manipulating data into tables/views?

Thank you.

There's no general "case_sensitive = yes/no" flag. There are case-insensitive
operators you can use though.

Is there a case insensitive locale? Or is that even possible?

I've heard it proposed, but don't believe anyone liked the idea enough to do
it. With my limited understanding of encoding/locale issues, that'd mean
adding support at the OS level, I think.

The other option would be an IVARCHAR type with suitably defined operators,
but that's hardly very portable.

It's certainly possible, but I don't know of any standard locales that
behave like that.

One could also imagine developing a new set of comparison operators that
do case-insensitive comparison, and then making a special index opclass
for that. The locale-insensitive operators Peter built to optimize LIKE
indexing in 7.4 would be a good model.
