Darn. Well, lemme put it this way: I'm not prepared to require that PG be deterministic at the physical level. One obvious source of non-determinancy is the FSM, which is likely to hand out different free space to different transactions depending on what else is going on at the same time. There are others, such as deliberately random tie-breaking during btree index insertion. regards, tom lane
