Old description:

> Sqlite supports case insensitive fields by setting COLLATE NOCASE.
> This works as you would expect for SELECT and INSERT.

> It would be great to have equivalents to the CIText fields in
> postgres.contrib - this would make it a lot easier to unit test code
> using those fields.

Comment (by Stuart Axon):

 Cheers, I did send an initial mail to the dev list, but think it might
 have got eaten as I didn't see it (also had a bit of bad luck updating
 this ticket, updating the description, not leaving a comment).

 One thing I found out, is that even with COLLATE NOCASE sqlites regexes
 don't default to case insensitive, so that would need some support at the
 django end.

 I had a bit of a look into how the postgres citext works, but couldn't
 work out how to make Operators that integrate with Django in the same way.
 I guess a really tiny implementation, as fields.py might be a start ?
