If json generation from built-in types is complete with full coverage of
all useful types when this first ships, then I'm happy. I was only
concerned about the BC argument "you can't add a proper json-aware cast
from interval to json because we've already been doing it via a cast to
text and changing the result would break existing code".
That's all I'm worried about, and if that won't be an issue then I'm
perfectly happy.
