Thread: json functions
Hi,
I have PostgreSQL 9.2.1. I can see a few json functions under pg_catalog, json_send, for example. But I can’t find any documentation. Am I missing something?
Regards,
Jayadevan

I am sure you are looking for that: http://www.postgresql.org/docs/9.2/static/datatype-json.html http://www.postgresql.org/docs/9.2/static/functions-json.html Note that 9.3 has far more features related to json: http://www.postgresql.org/docs/9.3/static/functions-json.html -- Michael

Not all functions available in the catalog are exposed through SQL -- for example they may be used to serialize data for transmission over the wire. If you can handle C you can hunt down the location of the function to see what it does (which isn't much since json is an already serialized format). merlin

I was wondering why we have quite a few functions under pg_catalog and just a few in the documentation.Thank you.
