Scripting that should not be needed, except that tools are generally
crappy :(

Yes, it's definitely already useful. If you check
https://codecov.io/gh/postgresql-cfbot/postgresql/commits you can see
the code coverage for the various CF entries. Both the absolute coverage
and, more interestingly, the coverage of the changed lines. There's some
noticeable difference in coverage between the various entries...
E.g. very little of the new stuff in
https://codecov.io/gh/postgresql-cfbot/postgresql/commit/ceaa3dbece3c9b98abcaa28009320fde45a83f88
is exercised.

A lot of these probably are too slow to be practical... I know it's not
fun, but a good bit of that probably is going to be making the UI of the
overview a bit better. E.g. direct links to the build / tests logs from
travis/codecov/..., allowing to filter by failing to apply / failing
tests / ok, etc...
Some of this would be considerably easier if the project were ok with
having a .travis.yml in our sourcetree.

Andres
