Re: Deleting 173000 records takes forever, blocks async queries for unrelated records

Or this?

DELETE FROM pref_users
WHERE id IN (
    SELECT id
    FROM pref_users
    WHERE id NOT IN (
        SELECT DISTINCT id
        FROM pref_money
    )
    LIMIT 10
);

Saw elsewhere another suggestion with EXCEPT, which is also sexy.
