I don't think that will help; if the overall row size is below the
threshold, the code is not going to pick it apart to see if anything
is saying "toast me anyway!". And it shouldn't do so IMHO; the overall
cost in cycles would be catastrophic, because most tables aren't going
to have such columns.
There was discussion just yesterday of making the TOAST thresholds
more configurable, but I didn't see anyone stepping up with a
concrete proposal (much less volunteering to create a patch).
