The code is currently enabled in trunk and is still awaiting review. It's basically complete, but there are some issues left:
* What sortkey algorithm to use? Currently it just ASCII uppercases the words, which is okay for a proof-of-concept but doesn't actually solve bug 164. * What should be done about compatibility, particularly given the schema change? Should I try to convert all the extensions I've broken? Should we keep the old cl_sortkey index so that out-of-tree uses don't suddenly become extremely inefficient (but then we have to maintain an extra largely pointless index)? * On a much more minor note, cl_sortkey should probably be redefined to varbinary(255), instead of varchar(70). I'd do this, but I'm not totally sure about it, so I'm awaiting feedback from Tim, since it would be annoying to convert it and then convert it back.
