-- 168_fdw_osm_poi_ekb.sql
-- FDW foreign table bridging to gendesign's v_tradein_osm_poi_ekb view for
-- location-coef / POI scoring in LocationDrawer (#2045, BE-3 final PR).
--
-- Mirrors 060_postgres_fdw_extension.sql conventions: uses the SAME SERVER
-- gendesign_remote (already created there) — this migration does NOT create a new
-- SERVER / USER MAPPING.
--
-- DEPENDENCIES:
--   - 060_postgres_fdw_extension.sql (SERVER gendesign_remote + USER MAPPING, managed by
--     backend startup with env password).
--   - gendesign: view public.v_tradein_osm_poi_ekb + GRANT SELECT to tradein_fdw_reader
--     (PR-A of #2045, already merged + deployed on gendesign).
--
-- Idempotent: DROP FOREIGN TABLE IF EXISTS + re-CREATE.
