Another update - what broke it was not the enabling of autovacuum, it was the enabling of row level stats. If I disable stats_row_level, parallel tests pass again. That doesn't actually tell us *why* it's broken, I think, but it does tell us why the autovac patch caused it. I don't have 8.1 or 8.2 around on win32, but it'd be interesting to see if the same issue happens if you run the tests on that with stats_row_level enabled. Most likely the same thing happens. //Magnus
