I posted this in November
https://postgr.es/m/20191101203310.GA12239@alvherre.pgsql but I didn't
put time to go through the issues there. I don't know if my approach is
exactly what Andres has in mind, but I was discouraged by the number of
gotchas for which the optimization I propose has to be turned off.
Maybe that preliminary patch can serve as a discussion starter, if
nothing else.
