I was suspicious of those as well. It might be a good idea to at least write such failures to stderr, otherwise it's just about impossible to debug. Not that stderr will always point anywhere useful... I can imagine that a system under heavy memory pressure might fail writing, if there's a lot of writes in a row or such. Greetings, Andres Freund
