You really need to explain why this matters...
You mention a "typical Ruby on Rails app" and then discuss SQLite.
Well, typical web apps have more than 1 user, so fairly obviously
using SQLite isn't appropriate. If SQLite isn't appropriate, why are
you testing with it? How does a test run on a database you aren't
using in production tell you anything about the success or otherwise
of your program. It doesn't, so saying it runs quicker is irrelevant,
surely?
Perhaps just run half the test, that would make it twice as quick and
still just as valid.
If Postgres tests run in ~1 minute, what benefit have you gained from
saving 30 seconds? How often are you running tests?
So please explain a little more.
