I think the relevant precedent is that we have an xml type.  While I
surely don't want to follow the SQL committee's precedent of inventing
a ton of special syntax for xml support, it might be useful to look at
that for suggestions of what functionality would be useful for a json
type.

[ I can already hear somebody insisting on a yaml type :-( ]
