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.
