Sean Griffin 4ef072ff99 Index columns used in migrations
We were benchmarking queries without sufficient indices, causing
inconsistent performance characteristics. For example, changing
`hair_color.eq("black")` to
`hair_color.eq("black").or(hair_color.eq("blue))` would cause SQLite to
perform between 2-10 times better depending on the number of rows. By
adding these indexes, we ensure that our benchmarks perform more
consistently
