In reply to: Why json
Parent article: PostgreSQL 9.2 released
Right now it's #3 with validation, plus some functions to turn result sets or arrays into structured JSON for easy consumption in applications. That's the main benefit at this point.
However, future versions are extremely likely to add enhancements like:
- Indexing, like hstore currently has
- Operators or functions to merge json objects, extract values, get key lists, etc like the hstore and xml support have
- More features for constructing and consuming JSON in the DB
Because Pg is so extensible, much of that is likely to be available as backports into 9.2.
