Produces output like this...
DEBUG:ARC T1target= 45 B1len= 4954 T1len= 40 T2len= 4960 B2len= 46
DEBUG:ARC total = 98% B1hit= 0% T1hit= 0% T2hit= 98% B2hit= 0%
DEBUG:ARC buffer dirty misses= 22% (wasted= 0); cleaned= 4494
when you have debug_shared_buffers (= n) set
and you have server messages DEBUG1 available.
The last line of log output has been replaced by this version.
