Hm, I think 0ba06e0 is actually the relevant change here? Though 40cfe86 was a necessary cleanup fix. I'm too tired to dig in the buildfarm database to be sure, but my impression is that the failure rate is much-better-but-not-zero. So I'd support back-patching those two commits, but I'm not sure if that's the end of the conversation. regards, tom lane
