Well, here we go again.
? My third year in a row talking about JSON at FOSDEM.
? A lot has changed in the last year. ? PostgreSQL 9.4 has a ton of new JSON
features.
? Let's take a look.
JSON, what is?
? JavaScript Object Notation. ? A text format for serializing nested data
structures.
? Based on JavaScript's declaration syntax. ? Intended to be passed directly into
JavaScript's eval() function (don't do this!)
JSON Primitive Types.
? Strings, always Unicode. ? De facto, always UTF-8 in flight. ? Numbers, integer and float. ? Boolean: true and false.
? null
