So, Heikki, are you planning to work more on that and commit a change
close to what has been proposed upthread in [1]? It sounds to me that
this has the advantage to be non-intrusive and a similar solution has
been used for GIN indexes. Moving the redesign out of the discussion,
is there actually a downsize with back-patching something like
Heikki's version?
Tom, Alvaro and Julien, do you have more thoughts to share?
