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.
