I don't think that there is any fundamental reason why VACUUM cannot have repeatable results. Anyway, I suppose it's possible that problems reappeared here due to some other patch. Something else could have broken Andres' earlier band aid solution (which was to set synchronous_commit=on in test_setup). Is there any patch that could plausibly have had that effect, whose commit fits with our timeline for the problems seen on wrasse? -- Peter Geoghegan
