Request for comment: pgjson project

Hi all -
http://github.com/tlaurenzo/pgjson

I'm a long-time postgres user but have never developed any extensions for
it. I had some time over the past week and decided to tackle a project I've
had on my list for a while: adding robust JSON capabilities to the database
server. This is the first step in a bigger thought that I've been toying
with for a while.

Its not done yet, but it builds and works with some examples (see the Github
readme).

This isn't just an alias for a text type with some validation. The internal
representation is actually a superset of BSON (http://bsonspec.org/) as
defined for MongoDB. I've architected it so that it should play naturally
with the postgres type system, but there are still some cast functions that
need to be implemented.

Anyway, feedback is appreciated - good, bad or otherwise.

Thanks.
Terry
