havebeen implemented so far. When a checkpoint is triggered, the performance jitter of PostgreSQL is very noticeable. I

Well, that thread is 12 years old, and no one followed on that proposal.
So it seems people have different priorities, working on other stuff
that they consider is more valuable ...

You can either work on this yourself and write a patch, or try to
convince others it's worth working on. But you didn't provide any
information that'd demonstrate the jitter and that incremental
checkpoints would improve that.
