I didn't have time...

I'll see if I can find a decent place to document how to tweak the
threshold, as that seems like it could be worth doing in cases where
it is known that there is benefit to TOASTing smaller tuples for one's
well-understood workload.

(e.g. - we've got a case where dropping the threshold to ~900 bytes
would give us a big win for certain databases and tables.)
