-- Migration: Fix deduplication constraints and clean up duplicate rows
|
|
|
|
-- 1. Deduplicate attachments
|
|
DELETE FROM attachment a
|
|
USING attachment b
|
|
WHERE a.announcement_id = b.announcement_id
|
|
AND a.url = b.url
|
|
AND a.id > b.id;
|
|
|
|
-- 2. Unique constraint for attachment idempotency
|
|
DO $$
|
|
BEGIN
|
|
IF NOT EXISTS (
|
|
SELECT 1 FROM pg_constraint WHERE conname = 'uq_attachment_announcement_url'
|
|
) THEN
|
|
ALTER TABLE attachment ADD CONSTRAINT uq_attachment_announcement_url UNIQUE (announcement_id, url);
|

END IF;

|
|
|
-- 3. Fix invalid self-referencing canonical_id
|
|
UPDATE announcement SET canonical_id = NULL WHERE canonical_id = id;
|
|

-- 4. Clean duplicate positions and add unique index
|
|
DELETE FROM position a
