I would prefer to abort the thread whose connection got an error and report
results for other threads, as handled when doConnect fails in CSTATE_START_TX
In this case, we have to set the state to CSTATE_ABORT before going to 'done'
as fixed in the attached patch, in order to ensure that exit status is 2 and the
result reports "pgbench: fatal: Run was aborted; the above results are incomplete."
Otherwise, if we want pgbench to exit immediately when a connection error occurs,
we have tocall exit(1) to ensure the exit code is 1, of course. Anyway, it is wrong
that thecurrent pgbench exit successfully with exit code 0 when doConnnect fails.
