I just verified that adjusting oom_score_adj will also adjust oom_adj,
so the kernel indeed just has one score, and is just providing a
backwards compatible interface for oom_adj.

That's not quite correct, as oom_score_adj has a different range
(-1000 to 1000). But it's easy enough to fix anyway.
I fixed pg_ctlcluster in bzr now, thanks!
I'm cloning the bug for -9.1, as the postmaster raises the backends
back to 0, and also uses oom_adj.
