It looks to me like you're running into the same issue described here:
namely that a toasted datum is still in memory after the owning table
has been dropped, and so subsequent attempts to expand the datum fail.
I'm not sure there is any really nice fix for that --- the easy fix
of forcibly detoasting everything before plpgsql stores it anyplace
would have very unpleasant performance implications. Needs more thought.
Curious that this behavior has been there unremarked since 7.1 or so
and now two different people stumble across it within a couple of weeks
of each other.
