JSON question

Hi All

    I'm experimenting with PostgreSQL's JSON features and have a question.   

    Say we have the following JSON (which will be stored in a table named 'resources' - in its 'schema' column ...

{

  "name": {

    "type": "string",

    "label": "Name",

    "accessor": "name",

    "is_association": false

  },

  "books": {

    "type": "array",

    "label": "Books",

    "accessor": "books",

    "is_association": true

  },

  "email": {

    "type": "string",

    "label": "Email",

    "accessor": "email",

    "is_association": false

  },

  "date_of_birth": {

    "type": "date",

    "label": "Birthday",

    "accessor": "date_of_birth",

    "is_association": false

  }

}

    [NOTE: the JSON above is the 'schema' attribute of one record in the 'resources' table.   There will be many rows in the 'resources' table]

    How can I query the 'resources' table to return the rows in which there's at least one JSON object whose 'type' equals 'array' ?

Thanks
