Обсуждение: case sensitivity?

Hi

I posted a similar question before. I was told that Postgres is always case sensitive.
I was actually referring to text data not identifiers.
I mean char and varchar fields.
I basicically want to avoid using upper in comparisons.
With some databases you can use a utf8 characterset and a unicode or win1252 coallation.
Has anyone tried this?
Do you know if this will work?

Thanks

H.F.

Maybe the citext type would do what you want?

There's a contrib module that will allow you to do this.  See the
citext datatype.
