We should build a test harness that runs a collection (possibly all) of places queries against an average and a maximum databases, build using telemetry data. This may be largely more useful than the current dirty tests and prevent bugs due to SQLite Query Planner changes or poor ANALYZE statistics or just queries regressions.

note that bug 708413 is sort of this in the wild, the difference is that this will be a sort of prevention while that one is rather a sort of post-detection and cure.

sigh, I meant bug 699051.
