Recording Release date in Database dump

That query will give you all release dates for all recordings, not just the earliest ones. You’ll have to sort them. Here’s what the server uses if the recording_first_release_date table is empty:

SELECT DISTINCT ON (track.recording) track.recording,
    rd.date_year AS year,
    rd.date_month AS month,
    rd.date_day AS day
FROM track
JOIN medium ON medium.id = track.medium
LEFT JOIN (
    SELECT release, date_year, date_month, date_day FROM release_country
    UNION ALL
    SELECT release, date_year, date_month, date_day FROM release_unknown_country
) rd ON rd.release = medium.release
WHERE track.recording = ?
ORDER BY track.recording,
    rd.date_year NULLS LAST,
    rd.date_month NULLS LAST,
    rd.date_day NULLS LAST;

Replace WHERE track.recording = ? with whatever condition you’re using.
