Hm, what I'd try after a bit of thought is to stuff the same data
into two different tables with different settings chosen to make it
TOAST or not, and then just test the toast tables for zero or nonzero
size. Setting STORAGE = EXTERNAL on the data column to disable
compression would help make things more stable, too.
