Architecturevector-rag / Postgres-native full-text and vector search
DetailsParadeDB is a PostgreSQL extension (pg_search + pgvector integration) that brings Elasticsearch-quality BM25 full-text search and hybrid vector search directly inside Postgres. It eliminates the need for a separate search engine by adding inverted index structures natively. Logical replication from existing Postgres instances is supported, requiring no ETL pipeline.
