Improving pgbench to log index creation time etc.

What do you think?

I propose doing this unconditionally. Adding an option seems too
complicated.

Hi PostgreSQL hackers,
I often need to calculate time to spend for index creation and vacuum
to analyze PostgreSQL data load performance. Index creation and vacuum
will take non trivial time for large scale data and it is important
information of data loading benchmark.

So I would like to propose to add new options to be used with pgbenh
-i (initialize) mode:

--log-index-creation-duration: log duration of index creation in seconds
--log-vacuum-duration: log duration of vacuum in seconds

What do you think?

I would think if you wanted that, you could set up a custom script that
does CREATE INDEX and/or VACUUM. The built-in scenario isn't all that
interesting...
