+-- Migration 069: close the concurrent-insert duplicate-URL race on poi_news.
+--
+-- saveNewsItems dedups with a SELECT-then-INSERT, which has no DB-level guard:
+-- two concurrent collection branches can both read "not present" and both
+-- insert the same URL (observed repeatedly on the historicbridges POI, e.g.
+-- ids 1523/1524 and 2622/2623 inserted ~24ms apart). A unique index on the
+-- normalized source_url turns that race into a clean no-op when paired with
+-- ON CONFLICT DO NOTHING in the insert path.
+--
+-- Events are intentionally excluded: distinct events legitimately share a
+-- generic source URL (a venue homepage or calendar page), so source_url is not
+-- unique for poi_events.
+
+-- Safety net: collapse any pre-existing normalized-URL duplicates before adding
+-- the constraint, keeping the best row per URL (published > pending > rejected,
+-- then lowest id). Idempotent -- a no-op once the table holds one row per URL.

+USING poi_news b
+WHERE a.source_url IS NOT NULL
