-- There was a bug where we may have updated censored redactions as bytes,
-- which can (somehow) cause json to be inserted hex encoded. This goes and
-- undoes any such hex encoded JSON.
UPDATE event_json SET json = convert_from(json::bytea, 'utf8')
WHERE event_id IN (
SELECT event_json.event_id
FROM event_json
INNER JOIN redactions ON (event_json.event_id = redacts)
WHERE have_censored AND json NOT LIKE '{%'
);
