Hi Markus, It is not related to fork maps. The idea is to learn PostgreSQL process to read old data page structures. It is part of in-place upgrade and it was discussed on PGCon this year. You can see more info on http://wiki.postgresql.org/wiki/In-place_upgrade http://www.pgcon.org/2008/schedule/events/87.en.html This is prototype of first part. Multi versions tuple processing and tuple size limits are next part.
