The libpq client (error log:
http://dbt.osdl.org/dbt/dbt2dev/results/dev4-015/180/client/error.log)
is saying things like this:
ERROR: too many LWLocks taken
CONTEXT: SQL statement "DELETE FROM new_order
WHERE no_o_id = 2101 AND no_w_id = 349 AND no_d_id = 1"
A grep through that file shows that all the unexpected errors appear to
be due to "too many LWLocks taken".
