500 kB is not too much for Postgres, but maybe is too for your client.

The most simple way is using Large Object interface - you can use psql
command \lo_import. Next step is converting imported large object to
string. An example is demonstration of import large JSON document.

postgres=# \lo_import ~/citylots.json
lo_import 16510
CREATE OR REPLACE FUNCTION public.bytea_to_text(bytea)
 RETURNS text
 LANGUAGE sql
AS $function$
SELECT convert_from($1, current_setting('server_encoding'))
$function$

CREATE TABLE city_text(data text);
INSERT INTO city_text SELECT bytea_to_text(lo_get(16510));
CREATE TABLE city_json(data json);
CREATE TABLE city_jsonb(data jsonb);
INSERT INTO city_json SELECT data::json FROM city_text;
INSERT INTO city_jsonb SELECT data::jsonb FROM city_text;

Probably this is not PostgreSQL bug - please, use psql-general mailing list.
