   Usually py.test lists tests directories in alphabetical order:
"include/tests inheritance/tests tests versioning/test". I put "tests"
at the front: "tests include/tests inheritance/tests versioning/test"
and that fixes the problem both locally and at CIs.

   Could be, but why only with Postgres then?

           Programmers don't die, they just GOSUB without RETURN.
