It doesn't seem that unusual to want to rename an index on a running
system, and it certainly doesn't seem like the kind of operation that
should pose a problem. So at the very least, we'd need a big fat warning
in the docs about how renaming an index could cause other queries in the
system to fail, and the error message needs to be improved.

it is my understanding that Tom is already tackling the underlying issue
on a much more general base ...

Done in HEAD, but we might still wish to think about changing the
regression tests in the back branches, else we'll probably continue to
see this failure once in a while ...

How sure are we that this is the cause of the problem? The feeling I got was "this is a good guess". If so, do we want to prevent ourselves getting any further clues in case we're wrong? It's also an interesting case of a (low likelihood) bug which is not fixable on any stable branch.
