Sure, but my point was that once the new reindexdb is released (or if
you're so desperate, using a nightly build or compiling your own), it
can be used against any previous major version. There is probably a
large fraction of users who don't perform a postgres upgrade when they
upgrade their OS, so that's IMHO also something to consider.
