-- 185_tradein_osm_poi_view.sql
-- Issue #2045 (trade-in location-coef/POI, PR 1 of 2 — gendesign side only).
-- Exposes osm_poi_ekb (82_osm_poi_ekb.sql) to tradein-postgres via the existing
-- postgres_fdw bridge / tradein_fdw_reader role (100_tradein_fdw_role.sql).
-- Mirrors v_tradein_cad_buildings: flat, minimal column slice + freshness filter,
-- GRANT SELECT to the already-existing role (no new role / no user mapping here).
--
-- Second PR (FDW foreign table + service in tradein-mvp) lands separately AFTER
-- this migration is deployed on gendesign.
--
-- Idempotent: CREATE OR REPLACE VIEW + repeatable GRANT.
