Maybe we should bite the bullet and provide

Yeah, Robert has just convinced me, so I'll do it like that. It doesn't
look too hard.
Oh, I have a better idea. We're only going to need all this for
pass-by-ref types, right?
Yes, the value we get back for byval types isn't a pointer that might disappear.
Why not make the hash key be the value
itself? Wrap it in a bytea perhaps to avoid needing a bespoke
hash function.
Not sure I understand.
