I already whined about this at [1]. I've been wondering if the issue could be traced to topminnow's unusual hardware properties, specifically that it has MAXALIGN 8 even though it's only a 32-bit machine per sizeof(void *). I think the only other active buildfarm animal like that is my gaur ... but I've failed to reproduce it on gaur. Best guess at the moment is that it's a timing issue that topminnow manages to reproduce often. Anyway, as I said in the other thread, I can reproduce it on topminnow's host. Let me know if you have ideas about how to home in on the cause. regards, tom lane [1] https://www.postgresql.org/message-id/111657.1650910309%40sss.pgh.pa.us
