Unfortunately, the only real way to change the collation right now is to
re-initdb with LC_COLLATE set to something else in the environment. The
index order for btree indexes is dependant on the collation order so
changing it after the fact would be bad.  This does mean dumping and
reloading or some kind of replication to get the data between the old
system and new.
