I notice that the buildfarm appears to run initdb with syncing enabled
("syncing data to disk ... ok" in the initdb steps).  Whereas pg_regress
uses --no-sync.

I wonder if that's what makes the difference? Now that you reproduced
it, does it still reproduce with --no-sync added?

Also worth noting that pg_regress doesn't go through pg_ctl...
