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.

Thank you for your interest in this problem and help, and I'm sorry
that I didn't respond to this email for a long time. To be honest, I
wanted to investigate the problems in more detail and already answer
more clearly, but unfortunately I have not found anything more
significant yet.
What is the status of this patch? It is registered in the commitfest.
It looks like a stalled research project? The last posted patch
doesn't contain any description or tests, so it doesn't look very ready.
