Metrics over time about pghero

[sj26]

Index usage over time would be amazing. I frequently modify and optimise queries, or create alternate indexes, and manually keep track of index usage stats to see if I'm effective. Having a historical set of index usage stats with a nice chart would make this much easier.

I'd still really like this feature!

Mainly for index usage over time to see if an index becomes unused.

Awww, I also liked the idea of this feature but my guess is that this would best be solved by a PR. I'm glad this project still has @ankane 's attention though. Thanks for all your hard work!
