I'm having a hard time imagining how you'd actually implement that.
For example, this:

https://wiki.postgresql.org/wiki/Aggregate_Histogram

requires that a "limit" be specified ahead of time. Is there a
principled way to increase or decrease this kind of limit over time,
and have the new buckets contents "spill into each other"?
