That's a fair question.

We find that most developers storing time-series data on Postgres are doing so without pg_partman. So we first wanted to provide a benchmark that would be useful to most developers.

This benchmark was also the result of months of dedicated work. So the team did spend a lot of time on this. Unfortunately, they ran out of time to cover pg_partman. But that comparison is on our list of things to do soon.

Thanks!
