-- Reclaim the dead tuples the backfill left behind (it updated ~every row, so the
-- table is ~2x bloated) and refresh planner stats so queries pick up the new
-- indexes. Standard VACUUM (not FULL) — online, no exclusive lock, but it does a
-- full heap + index scan so it can take a while. No progress output; watch
-- pg_stat_progress_vacuum in another session.
