Yeah.  I think we had a TODO to figure out a way for the assign_hook to
report back exactly which values *are* allowed on the current platform.
Constructing the message for this doesn't seem very difficult, but the
rules about when assign_hooks can issue their own elog message seem
to constrain the usefulness...
