   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   A clear and concise description of what the problem is. Ex. I'm always 
frustrated when [...] 
   (This section helps Arrow developers understand the context and *why* for 
this feature, in addition to  the *what*)
   
   Not sure if this is a bug of a feature request but running the query 
contained in #4005 pushes down a somewhat unexpected predicate
   
   ```
   explain select * from foo where container = 'backend_container_0' OR pod = 
'aqcathnxqsphdhgjtgvxsfyiwbmhlmg';
   
   ...
   |               |         ParquetExec: limit=None, 
partitions=[home/raphael/Downloads/data.parquet], predicate=container_min@0 <= 
backend_container_0 AND backend_container_0 <= container_max@1 OR pod_min@2 <= 
aqcathnxqsphdhgjtgvxsfyiwbmhlmg AND aqcathnxqsphdhgjtgvxsfyiwbmhlmg <= 
pod_max@3, projection=[service, host, pod, container, image, time, client_addr, 
request_duration_ns, request_user_agent, request_method, request_host, 
request_bytes, response_bytes, response_status] |
   ```
   
   In particular the equality predicates appear to be being split into a `<=` 
and a `>=`, effectively doubling the work to evaluate them.
   
   **Describe the solution you'd like**
   
   I would expect the minimal set of predicates to be pushed down
   
   **Describe alternatives you've considered**
   
   
   **Additional context**
   
   FYI @alamb
