Perhaps. I tried "make check" on mamba's host and got exactly the
same failures as with "make installcheck", which counts in favor of
dodo's results being just luck. Still, dodo has now shown 11 failures
in "make installcheck" and zero in "make check", so it's getting hard
to credit that there's no difference.
