ERRCODE_WRONG_OBJECT_TYPE (42809) seems like a better match. The
prerequisite-state error implies that you could have done that operation
on that object, if it were in a more receptive mood.
The 42xxx series covers pretty much anything in the
what-were-you-thinking category, AFAICS. If I'd been on the committee
I would have broken it down a bit more...
