I mean what Robert has mentioned here:
https://www.postgresql.org/message-id/CA+TgmoZ4TWaPCKhF-szV-nPxDXL40zCwm9pNFJZURvRgm2oJzQ@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.
