What do you mean by "delaying the checkpointer"?
I mean what Robert has mentioned here: https://www.postgresql.org/message-id/ca+tgmoz4twapckhf-szv-npxdxl40zcwm9pnfjzurvrgm2o...@mail.gmail.com And my gut tells me that he got that right, because we are discussing about race conditions with crashes and checkpoints in-between calls to smgrimmedsync() and log_newpage(). That could be invasive for back-branches, but for HEAD this would make the whole init fork handling saner. -- Michael
