One of the problems I saw, and that's probably why we don't have a proposal yet, is, that the size of the
data is recorded in the toast reference held in the main tuple. If you later open the toast value for writing,
you'llchange the size, but you'd need to change it in the main tuple too, what'd require a regular update on
the main tuple, what I don't think we want to have here.
The other problem is, if you insert a tuple containing a small value (e.g. empty string), it'll not get
toasted and you can't force it to get. Later you open it for writing and pump a CD-image into. How do we convert
the existing empty text datum into a toast reference in the main tuple?
