Hi,

I'm trying to get my get my head around pg_rewind.
Why does it need full_page_writes and wal_log_hints on the target?
As far as I could see it only needs old target WAL to see what pages 
have been touched since the last checkpoint before diverge point.
Why can't it get this data from partial pages?

Best, Alex
