Improve logging of autovacuum I/O activity This adds some I/O stats to the logging of autovacuum (when the operation takes long enough that log_autovacuum_min_duration causes it to be logged), so that it is easier to tune. Notably, it adds buffer I/O counts (hits, misses, dirtied) and read and write rate.
