Support JSONB to query parameter conversion for GET in http

[kolpav]

Unlike http_get, the http function does not automatically convert JSONB payloads into query parameters for GET requests.
Would it be a good idea to add similar behaviour to http for consistency? Or maybe make http_get also accept http headers? Thats the main reason I am using http instead of http_get. Great project btw 👍

In http_get, JSONB data is automatically URL-encoded and appended to the URI

SELECT * FROM http_get('https://api.example.com/resource', jsonb_build_object('param1', 'value1'));

With http, this has to be done manually

SELECT * FROM http((
  'GET',
  'https://api.example.com/resource?' || urlencode(jsonb_build_object('param1', 'value1')),
  ARRAY[http_header('Authorization', 'Bearer token')],
  NULL,
  NULL
)::http_request);

By reading README.md I was expecting this would work

SELECT * FROM http((
    'GET',
    'https://api.example.com/resource',
    ARRAY[http_header('Authorization', 'Bearer token')],
    'application/x-www-form-urlencoded',
    jsonb_build_object(
      'param1', 'value1'
    )
  )::http_request);

The thing is, the http() function is very much designed to just take a request. The structural difference between a GET and a POST also makes things a little hard to paper over, since in one case the data payload is going into the URL, and in another case it's going into the content. Maybe a parameter on the specialized http_get for headers is better... I was also thinking that a variadic function to create the headers array might also help in that case.
