Well, it's the same "odd error" you'd get for any other bogus OID.
The way the function is coded, it has no need to look into pg_tablespace
as such, which is why you don't get something like "no such tablespace".
We could add such a lookup purely for error detection purposes, but I'm
not real sure I see the point.

That's a consequence of the function being marked strict; it has nothing
much to do with anything.
