Hi!

When I sent the patch version to commitfest, I thought that the work on 
this topic was completed. Patch version and test results in [0].

But in the process of discussing this patch, we found out that there is 
another place where you can make a transformation, specifically, during 
the calculation of selectivity. I implemented the raw version [1], but 
unfortunately it didn't work in regression tests.

I'm sorry that I didn't write about the status earlier, I was very 
overwhelmed with tasks at work due to releases and preparations for the 
conference. I returned to the work of this patch, today or tomorrow I'll 
drop the version.
