Wiki / Functions

Collects all the key/value pairs into a JSON object. Key arguments are coerced to text; value arguments are converted as per to_json or to_jsonb. The key cannot be null. If the value is null then the pair is skipped. If there is a duplicate key (including pairs with null values) an error is thrown.

English manual coverage begins with PostgreSQL 7.1. Source history and runtime observations have their own recorded version boundaries.
