Fair enough. The situation is bad enough that I'm willing to consider a
pretty wide range of solutions and mitigations that might otherwise be
unappealing.
I think there might be something promising in your idea to highly
restrict the privileges of code attached to a table. A lot of
expressions are really simple and don't need much to be both useful and
safe. We may not need the exact same solution for both default
expressions and triggers. Some details to work through, though.
