Re: Best way to populate nested composite type from JSON`

Yup.  As things stand currently, it's better *not* to make
serialization-driving composite types which when learning the json
stuff I did heavily; it was a habit I learned (and had to unlearn)
from libpqtypes which solves a lot of the same problems for C clients.
 You can *almost* send json back to the database with the same
elegance as it can be sent out of the database.  I see a big future
for postgres-json with many roadmap improvements; it's a complete game
change for service call driven database interaction and forward
thinking developers should realize it essentially obsoletes ORMS.
