By persisting tsvectors in a dedicated column with a GIN index, query performance improved 118× (from ~283ms to ~2.4ms) on 100k rows. The optimization shifts PostgreSQL from sequential scans to bitmap index scans, reducing work from processing all rows to only matching ones. Implementation involves adding a tsvector column, creating a GIN index concurrently, setting up a database trigger for automatic updates, and configuring pg_search to use the persisted column instead of computing vectors at query time. ## Full article daily.dev links to this article rather than hosting it.
