Not at the time, no. The rename in question was just a regular WAL
segment rename.

Yeah, it's unfortunate that our best theory (a _commit on a deleted
file) just didn't seem to be supported by the evidence. Although the
servers which see a heavy SELECT load are now Linux, we still have a
couple of Windows servers receiving the normal replication traffic. We
still get regular fsync errors after the scheduled CLUSTERs so if you do
find a fix (or come up with a new theory), there's a test bed there (at
least for now).

We might be somewhat more susceptible than most too. Due to the way
our middle tier parcels out queries, some connections might sit idle for
a long time. Per Tom's explanation in the original thread, this is an
important factor. Ultimately if a concurrent rename isn't possible in
Windows (and that looks likely), it's going to be a problem as things
stand now.
