**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** We want to ordering `Expr`s in a consistent way in our tests. See details on https://github.com/influxdata/influxdb_iox/pull/2564 in https://github.com/influxdata/influxdb_iox/pull/2564#discussion_r710817261 This also is a necessary (but not sufficient) step towards being able to use `Expr`s in sets and maps (still need to implement `Ord` and `Hash`) which might have helped @waynexia in https://github.com/apache/arrow-datafusion/pull/792 with CSE and would help with other algebriac transformations in the future. **Describe the solution you'd like** `impl PartialOrd` for `Expr` **Describe alternatives you've considered** None **Additional context** None -- This is an automated message from the Apache Git Service.
