Yeah, I had considered that for a second or two, but didn't think it was
worth the trouble. 8.x releases are probably unlikely to get installed
on platforms that would have this issue.

It'd be better if someone could invent a plpgsql-free test case, anyway.
I'm not sure offhand why an eval fails to produce similar effects.
