Multi-Source Integration Phase 3.1. Foundation for /api/v1/search p95 < 100ms on 100K+ listings.
SQL 050_search_optimization.sql:
- CREATE EXTENSION IF NOT EXISTS pg_trgm
- ALTER listings ADD COLUMN tsv tsvector GENERATED ALWAYS AS (...) STORED
- 10 indexes (geom GIST, composite, gin_trgm, GIN tsv, partial kadastr, ...)
- CREATE MATERIALIZED VIEW listings_search_mv (per-listing aggregated across sources)
- 5 matview indexes (UNIQUE on listing_id for REFRESH CONCURRENTLY)
Celery task tradein.refresh_search_matview:
- REFRESH MATERIALIZED VIEW CONCURRENTLY listings_search_mv (psycopg v3)
- Logged duration via logger.info
- Graceful try/except ImportError fallback (no celery_app.py in tradein-mvp yet)
- Beat schedule snippet in docstring for future wiring
Fixups (deep-code-reviewer 2026-05-23):
- h.ratings_count → h.reviews_count (alias house_ratings_count preserved)
- Strip +psycopg dialect prefix from DSN for libpq compat
Refs Master Plan sec 5.1 + 6.5 + 10.1.
