More segments means more disk space taken up with them and a longer crash
recovery.  Those are the downsides; if you can live with those there's no
reason to run at <100 if that works for you.  Fine-tuning here isn't
really that helpful.

I'm a little confused by your report through because you should still be
seeing regular checkpoint warnings if you set checkpoint_warning = 3600s ,
they should just be spaced further apart.
