Fun. Agreed that this is a bug, and that the consequences are of
null for most users. And it took 7 years to find that.

If I may ask, is there an impact with functions that include SET
clauses with custom parameters that are parallel safe? Saying that,
if the fix is simple, I see no reason not to do something about it,
even if that's HEAD-only.
