-- ── Migration 011: Add route column to artboards FTS tsvector ────────────────
|
|
--
|
|
-- Problem:
|
|
-- Migration 006 created artboards.search_vector with only:
|
|
-- name (weight A) || metadata_jsonb::text (weight C)
|
|
-- The comment in 006 says route should be at weight B, but route didn't exist
|
|
-- until migration 007. Generated column expressions cannot be altered in-place
|
|
-- (pre-PG17) — the column must be dropped and re-added.
|
|
--
|
|
-- Fix:
|
|
-- Drop and recreate artboards.search_vector to include:
|
|
-- name (weight A) — exact component/screen name matches rank highest
|
|
-- route (weight B) — URL route matches rank highly (added by migration 007)
|
|
-- metadata_jsonb (weight C) — catch-all metadata text
|
|
--
|
|
-- Drop/re-add regenerates values for all existing rows automatically since
|
|
-- the column is GENERATED ALWAYS AS (stored computed column).
|
|
-- ─────────────────────────────────────────────────────────────────────────────
|
|
|
|
-- Drop the existing generated column (and its GIN index, which depends on it)
|
|
DROP INDEX IF EXISTS artboards_search_vector_idx;
|
|
|
|
ALTER TABLE artboards
|
|
DROP COLUMN IF EXISTS search_vector;
|
|
|
|
-- Re-add with route at weight B
|
|
ALTER TABLE artboards
|
|
ADD COLUMN search_vector tsvector
|
|
GENERATED ALWAYS AS (
|
|
setweight(to_tsvector('english', coalesce(name, '')), 'A') ||
|
|
setweight(to_tsvector('english', coalesce(route, '')), 'B') ||
|
|
setweight(to_tsvector('english', coalesce(metadata_jsonb::text, '')), 'C')
|
|
) STORED;
|
|
|
|
-- Rebuild the GIN index on the updated column
|
|
CREATE INDEX artboards_search_vector_idx
|
|
ON artboards USING GIN (search_vector);
