First, seems we'll have to follow to what you've proposed for
their redo/undo: log each *fact* of changing a page to know
was update op done entirely or not (rebuild index if so).
+ log information about where to find tuple pointing to heap
(for undo).
This is much easy to do than logging suitable for recovery.
