The following review has been posted through the commitfest application:
make installcheck-world:  tested, passed
Implements feature:       tested, passed
Spec compliant:           tested, passed
Documentation:            tested, passed

I can confirm that these patches don't break anything; the code is well
documented, has some tests and doesn't do anything obviously wrong. However
I would recommend someone who is more familiar with the VACUUM mechanism than I
do to recheck these patches.

The new status of this patch is: Ready for Committer

Commits

  1. Prefetch blocks during lazy vacuum's truncation scan

  2. Explain unaccounted for space in pgstattuple.
