title: Postgres: How to change the case of JSON keys?
body: <p>My address column is being stored as a JSON using this format:</p>
  
  <p><code>
  {
    "Street1": "800 Smithe St",
    "Street2": null,
    "City": "Vancouver",
    "Region": null,
    "State": "BC",
    "Zip": "V6Z 2E1"
  }
  </code></p>
  
  <p>How can I change the column values to camel case / lowercase, so they appear like this?</p>
  
  <p><code>
  {
    "street1": "800 Smithe St",
    "street2": null,
    "city": "Vancouver",
    "region": null,
    "state": "BC",
    "zip": "V6Z 2E1"
  }
  </code></p>
