When doing performance hacking on pg_upgrade it's often important to see
individual runtimes to isolate changes. I've written versions of the attached
patch numerous times, and I wouldn't be surprised if others have done the same.
Is there any interest in adding something like the attached to pg_upgrade? The
patch needs some cleaning and tidying up but I wanted to to gauge interest
before investing time. I've added it to verbose mode mainly since it's not
really all that informative for regular users I think.
