Hi Yugo and Fabien,
It seems the patch is ready for committer except below. Do you guys
want to do more on below?
>> # TESTS
>>
>> I suggested to simplify the tests by using conditionals & sequences. You
>> reported that you got stuck. Hmmm.
>>
>> I tried again my tests which worked fine when started with 2 clients,
>> otherwise they get stuck because the first client waits for the other one
>> which does not exists (the point is to generate deadlocks and other
>> errors). Maybe this is your issue?
>
> That seems to be right. It got stuck when I used -T option rather than -t,
> it was because, I guess, the number of transactions on each thread was
> different.

>> Could you try with:
>>
>> psql < deadlock_prep.sql
>> pgbench -t 4 -c 2 -f deadlock.sql
>> # note: each deadlock detection takes 1 second
>>
>> psql < deadlock_prep.sql
>> pgbench -t 10 -c 2 -f serializable.sql
>> # very quick 50% serialization errors
>
> That works. However, it still gets hang when --max-tries = 2,
> so maybe I would not think we can use it for testing the retry
> feature....
