#647-2 (P0, инфра — клиентскую цену НЕ меняет). Делает mv_quarter_price_index (#760) читаемым estimator'ом за O(1) + периодический refresh. - tradein 085_quarter_price_index_fdw.sql: FOREIGN TABLE quarter_price_index над main public.mv_quarter_price_index через существующий server gendesign_remote (паттерн 060_postgres_fdw_extension.sql, per-table). Колонки 1:1 с MV (varchar(30)/float8/bigint/text/timestamptz). DROP IF EXISTS идемпот. - main 99b_grant_quarter_price_index_fdw.sql: GRANT SELECT на MV роли tradein_fdw_reader (иначе foreign table падает; зеркало 122_grant_rosreestr). - main refresh: Celery beat (pg_cron нет). quarter_price_index_refresh.py — chained REFRESH mv_quarter_price_per_m2 → mv_quarter_price_index CONCURRENTLY; task refresh_quarter_price_index.py; beat-entry 'refresh-quarter-price-index' cron '0 2 5 * *' (05:00 MSK 5-го, после ekb-districts-medians). Lookup-индекс: MV уже несёт UNIQUE mv_quarter_price_index_uq (O(1) remote); foreign table не нуждается в локальном. Валидация (postgres-gendesign): MV 1972 строки, 0 NULL, UNIQUE indisunique=true, REFRESH CONCURRENTLY валиден. Разблокирует #647-3 (estimator integration, за гейтом #763).

-- 99b_grant_quarter_price_index_fdw.sql

-- Issue #762 (#647-2) — grant SELECT on mv_quarter_price_index to the tradein
|
||
-- FDW reader role so the tradein foreign table (085_quarter_price_index_fdw.sql)
|
||
-- can read it. Mirrors 122_grant_rosreestr_to_fdw_reader.sql.
|
||
--
|
||
-- Ordering: '99b_' sorts AFTER '99a_quarter_price_index.sql' (which CREATEs the MV)
|
||
-- because 'a' < 'b'. The MV must exist before the GRANT. Files 100_–122_ sort
|
||
-- BEFORE 99_ lexicographically ('1' < '9'), so they cannot grant on this object.
|
||
-- Idempotent: GRANT is repeatable; role tradein_fdw_reader created in
|
||
-- 100_tradein_fdw_role.sql (REVOKE ALL baseline there).
