Title: Change pg:seq_scans to become pg:scans

The absolute number of sequential scans isn't terribly meaningful on its own.

It's probably just as good an indicator of how long its been since there was a hard crash.

I'm not completely convinced that we should merge this pull request. Maybe it would be better to remove pg:seq_scans entirely, and unconfuse index_usage (thus closing #27).

Thoughts?
