There's currently no way for Postgres to efficiently query tests by status for a given build. The best query plan with the current setup is simply for Postgres to scan all of the tests for a given build. Scanning all tests is reasonably efficient in most cases, but the overhead adds up over time for this extremely common use case. This PR indexes
build2test(buildid,status)to allow the database to count the number of passing or failing tests directly.
