-- pg_trgm уже установлен в prod, но CREATE EXTENSION IF NOT EXISTS идемпотентен.

-- Trigram GIST index на comm_name (DOM.РФ) ускоряет LATERAL similarity() join

-- при поиске кандидатов для fuzzy match (domrf_kn_objects ↔ objective_corpus_room_month).

-- Dependencies: domrf_kn_objects, objective_corpus_room_month (уже существуют).

-- Applied: automatically via deploy.yml in NN order.
