FWIW, I've run 32 and 64 bit x86 through several hundred regression cycles, without hitting an issue. For a lot of them I set checkpoint_timeout to a lower value as I thought that might make it more likely to reproduce an issue. Tom, any chance you could check if your machine repros the issue before these commits? Greetings, Andres Freund
