   > [@sdf-jkl](https://github.com/sdf-jkl) that sounds great. IMO, preimage 
sounds misleading for something that's using interval containment to simplify a 
predicate, but maybe there will be other types of functions that can be 
reversed.
   
   The preimage terminology is from ClickHouse and I believe it refers to 
https://en.wikipedia.org/wiki/Image_(mathematics)#Inverse_image . 
   
   If you have a better suggestion on terminology perhaps we can change it 
before we release 53.0.0
