Not sure, but it seems like at least as straightforward a translation
as the other way. More to the point, it makes clear the difference
between what is meant to be a long-lived data structure and what isn't.

Why not? You'd need to keep the context-to-use in a static variable,
but that's no great difficulty considering that plpgsql function
parsing needn't be re-entrant.
