It would be great if some folks could find a moment to run the queries I
was showing on their data to confirm (or refute) my findings, or to
contribute to the picture in general.

As I was saying, the queries were designed in such a way that even
unprivileged user can run them (the results will be limited to the stats
data available to that user, obviously; and for custom-tailored statstarget
one still needs superuser to join the pg_statistic table directly).  Also,
on the scale of ~30k attribute statistics records, the queries take only a
few seconds to finish.
