log_autovacuum = on produces a single line of output from autovacuum,
with additional useful stats. Patch is proving useful in performance
testing. Not sure what is intended on logging for 8.3....

LOG: autovac "public.w" scans:1 pages:197(-0) tuples:2338(-7199) CPU
0.00s/0.00u sec elapsed 0.39 sec

tuples:37000611(-3461867) CPU 99.74s/53.37u sec elapsed 7977.20 sec

No docs yet, but will do this if accepted.
