Man, we've had a few problems with that thing, haven't we?
I patched it along these lines:

--- contrib/intagg/int_aggregate.c Sat Apr 23 01:32:52 2005

pc->flags = 0;
}
+ /* Now that we have a detoasted array, verify dimensions */
+ if (pc->p->a.ndim != 1)
+ elog(ERROR, "int_enum only accepts 1-D arrays");
pc->num = 0;
fcinfo->context = (Node *) pc;
MemoryContextSwitchTo(oldcontext);
