Re: pgbench: allow to exit immediately when any client is aborted

I have tested the v4 patch with default_transaction_isolation =
'repeatable read'.

pgbench --exit-on-abort -N -p 11002 -c 10 -T 30 test
pgbench (17devel, server 15.3)
starting vacuum...end.
transaction type: <builtin: simple update>
scaling factor: 1
query mode: simple
number of clients: 10
number of threads: 1
maximum number of tries: 1
duration: 30 s
number of transactions actually processed: 64854
number of failed transactions: 4 (0.006%)
latency average = 4.628 ms (including failures)
initial connection time = 49.526 ms
tps = 2160.827556 (without initial connection time)

Depite the 4 failed transactions (could not serialize access due to
concurrent update) pgbench ran normally, rather than aborting the
test. Is this an expected behavior?

Best reagards,
