Light1YT	57456b5d10	perf(tradein): GIST index on (geom::geography) for estimator radius filter (#1189 ) All checks were successful CI / changes (pull_request) Successful in 6s Details CI / backend-tests (pull_request) Has been skipped Details CI / frontend-tests (pull_request) Has been skipped Details CI / openapi-codegen-check (pull_request) Has been skipped Details Estimator analog query casts geom::geography for ST_DWithin, but listings_geom_idx is gist(geom) → spatial predicate fell to Filter, geom index used only for geom IS NOT NULL (54.5k-row scan, 180ms). Add gist((geom::geography)) expression index → ST_DWithin uses it as Index Cond. Prod dry-run (BEGIN/CREATE/EXPLAIN/ROLLBACK): 180ms → 38ms (~4.7x). Additive, idempotent (IF NOT EXISTS), non-destructive.	2026-06-26 22:09:01 +05:00
