Comment (by Florian Zimmermann):
Maybe worth noting: for me this depends on the `--parallel` option with
`--parallel 1` producing even more errors:
`--parallel 2` no errors:
{{{
> python runtests.py --settings test_postgres --parallel 2 postgres_tests
Found 590 test(s).
..........................................................................................................................x......x............x...............................................................................................................................................................................................................................................................................................................................................................................................................................................................
----------------------------------------------------------------------
Ran 590 tests in 7.974s
OK (expected failures=3)
}}}
`--parallel 4` two errors:
{{{
> python runtests.py --settings test_postgres --parallel 4 postgres_tests
Found 590 test(s).
