Hello Michaƫl,
Could you rebase the v11 patch?This patch has been waiting for a rebase for more than three weeks as of today, I am marking it as returned with feedback. It would be a good idea to reply to Robert's input in https://www.postgresql.org/message-id/ca+tgmoyybnv-ddhvpmxlb2nx2sqenjirtwhmdeazucgotb2...@mail.gmail.com.
ISTM that this was done: If -c is high enough, pgbench fails without the patch.
