This patch adds a count of the number of buffers dirtied to VACUUM, but it strikes me that it would be useful to add similar tracking to pgBufferUsage. Attached is a patch for that. You can see the new counters through pg_stat_statements or with EXPLAIN (ANALYZE, BUFFERS).
This looks pretty useful to me. I just threw it into the current CommitFest, on the basis that there's already so many other thing trying to whack around pg_stat_statements right now we might as well keep them together. Let me clear my queue of patches submitted on time I need to do something with (re-review Scott Mead's pg_stat_activity change, respond to Jeff Janes on relation free space) and I'll take a quick spin on this one.
