94 of the open issues on sqlc are related to the analyzer. There are many cases where the current analyzer produces false positives or false negatives. sqlx and some other projects have proven that it's possible to extract query metadata from a running database. This approach is a bit different, in that the database analysis is layered on top of the existing query analyzer. We use the new analysis to provide better type information and support a wider set of cases when the existing analyzer fails.
Add a `contexts` key to exec.json to opt certain tests into or out of database-backed analysis. Fix many incorrect test cases that didn't run against an actual database.

This PR is an obvious work in progress, but I'm happy enough with the result to share an early peek.
