Make getrusage() output a little more readable
The getrusage() output that is shown by VACUUM VERBOSE and other places
has always been a little too terse and confusing for me. I propose to
improve that a bit:
-CPU 0.01s/0.08u sec elapsed 0.18 sec.
+CPU: user: 0.08s, system: 0.01s, elapsed: 0.18s.Patch attached.
I have also updated the ShowUsage() output used by log_parser_stats etc.
to match this change, but I don't claim that that output is particularly
readable either way.
While updating the VACUUM man page I noticed that the example output
doesn't match exactly anymore, but I didn't do anything about that in
this patch, just changed the lines that are affected by this patch.

+1 for this change.
I have reviewed the patch and it seems fine.

I look at trace_sort output a lot, and do agree that this is confusing. +1.
