I've poked at this a bit more. There are at least 10 relations where the last block doesn't match the block mentioned in the xlog record that its LSN indicates. At least it looks like from the info xlogdump prints.
Including two blocks where the "correct" block has the same LSN which maybe means the record was correctlly replayed the second time. Or perhaps it just means I'm underestimating the complexity of btree splits.
