It's been a month and I haven't seen any new proposals. IIUC the main use case for inexact statistics is to estimate `num_rows` and `total_byte_size` using estimated selectivity, which itself is "inexact". So basically we need point estimates for those attributes, and exact bounds for the column min/maxes. Unless I'm misunderstanding, it seems like @crepererum's proposed API accommodates both of these use cases. Another open question is if we should try to unify `Interval` with `Precision`, but I think if we guard the internal values we will at least have the option to make this change going forward without breaking anything. I am interested in getting this change in so that I can resume work on #13296, so I am going to start pre-emptively working on a PR with the new `Precision` API. -- This is an automated message from the Apache Git Service.
