vacuum crash

I am wrong here. There is something else wrong.

I think I am on to something.

The funny way I update the system tables with vacuum optimization
information is wrong, I think, and the new cache code is properly
complaining about it.

I will keep testing. If I comment out the following code, the vacuum works.
Is there a better way to do this?

---------------------------------------------------------------------------

/* XXX -- after write, should invalidate relcache in other backends */
WriteNoReleaseBuffer(ItemPointerGetBlockNumber(&rtup->t_ctid));

/*
* invalidating system relations confuses the function cache of
* pg_operator and pg_opclass, bjm
*/
if (!IsSystemRelationName(pgcform->relname.data))
RelationInvalidateHeapTuple(rd, rtup);
