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.
