Yeah, I agree with the worry that a default value that's a mile long
is going to be a bit of a PITA. But I don't think we're there yet on
having a better solution.

If "default" always means what it means today, I can live with that.
But if the meaning of "all" changes from version to version, that seems
like a royal mess. Again, I'm concerned that an external tool like
pgfouine be able to make sense of the value without too much context.
If it doesn't know what some of the columns are, it can just ignore them
--- but a magic summary identifier that it doesn't understand at all is
a problem.
