That's not my intention at all. My intention is to justify the
validity of each index in our database. Some indexes have snuck in
that I find of questionable value, and I want the data to backup my
intuition.
Anyway, I'll look into the pg_stat* tables and see if those give me
the data I want. Thanks for the advice guys!
