I'm confused why you can't just pull portal_name from the json structure
using "->"
<https://www.postgresql.org/docs/current/static/functions-json.html>? For
example, assuming your json structure that looks like:

{"portal_name": "some data.."}

And a table that looks like:

| id | json_field |

Wouldn't this sql work:

select * from json_table
order by json_field->'portal_name'
