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...
