Because the original reporter seems to have difficulty to execute your test case immediately, I think I would try your test case. However unfortunately I have not succeeded in reproducing the stuck problem by using 9.4.4. I tend to think about increasing commit_delay and/or -c of pgbench and try it out again. Anything I should try other than this? Best regards, -- Tatsuo Ishii SRA OSS, Inc.
