Ejecutar SQL no funciona en psql

Estoy intentando ejecutar:

SELECT user_id, 0 post_id, current_timestamp granted_at 
FROM badge_posts  
WHERE (:backfill OR user_id IN (:user_ids) OR 0 NOT IN (:post_ids) )
GROUP BY user_id 
HAVING count(*) > 1000

pero estoy obteniendo un error en :backfill. ¿Alguien puede decirme por qué?

Sé que este SQL solía ejecutarse en la creación de insignias.

Anything starting with a : is a named parameter meant to be replaced by mini_sql prior to being sent to the DBMS, it’s not valid SQL by itself.

Example, see [2] below:

[1] pry(main)> User.find_by(username: 'anon43915857').id
=> 5

[2] pry(main)> DB.query(
  "SELECT id FROM users WHERE username = :username",
  { username: 'anon43915857' }
).first.id
=> 5

[3] pry(main)> DB.query(
  "SELECT id FROM users WHERE username = ?",
  'anon43915857' 
).first.id
=> 5
