What I think should happen is that if the value is changed, the index
sholud be rebuilt right there.  But there is no way to have this occur
from the generic tablecmds.c code.  Maybe we should extend the AM
interface so that they are notified of changes and can take action.
Inserting AM-specific code into tablecmds.c seems pretty wrong to me --
existing stuff for WITH CHECK OPTION views notwithstanding.
