This doesn't seem to break the existing behavior in 9.2.
Please find attached the patch to fix the problem. I changed to keep restored WAL files in pg_xlog/ only on a cascading standby server. Could you review and commit this?
BTW, KeepFileRestoredFromArchive() is also called to keep timeline history files in pg_xlog/. What is this for? Is this necessary for recovery other than cascading standbys? This seems to accumulate timeline history files forever in pg_xlog/.
