Before we get to the interface for reporting this to the client, I wonder how 
we should deal with this in the backend.  Right now, we have string options 
with assign hooks.  You'd need to add a reporting hook or something for each 
parameter.  I'm thinking, perhaps we should invent a new GUC data type enum, 
now that enum is an accepted way to categorize with data around here. :)  
That could simplify the code a bit.
