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.
