Big multiprocess workload and you kill individual processes at random
while letting the rest run. It probably needs to be something that
stresses more of the code than pgbench would, too. (For instance,
it'd be a good idea if some of the workload involved having a few 2PC
transactions getting prepared and then either committed or rolled
back ... SIGTERM during a COMMIT PREPARED strikes me as the sort of
corner case that's probably never been exercised.)
