Here's my proposed change to achieve that.

Here's an example of where it shows up if it fails (from my
deliberately sabotaged CI run
https://cirrus-ci.com/build/6730380228165632 where I was verifying
that it also works on Windows):

Unix: https://api.cirrus-ci.com/v1/artifact/task/5421419923243008/log/src/test/recovery/tmp_check/log/regress_log_027_stream_regress
Windows: https://api.cirrus-ci.com/v1/artifact/task/4717732481466368/log/src/test/recovery/tmp_check/log/regress_log_027_stream_regress
