paradedb vs pg_textsearch
PostgreSQL search extensions compared
paradedb and pg_textsearch both add ranked full-text search to PostgreSQL, letting teams query text without a separate search service. paradedb also covers vector retrieval and analytics, while pg_textsearch focuses on BM25-ranked text search and its PostgreSQL indexing workflows.
paradedb: Add Search and Analytics to PostgreSQL
ParadeDB is a PostgreSQL extension that brings full-text search, vector retrieval, and analytics into the database where application data already lives. It suits teams that want SQL-based search and aggregation without operating a separate search system.
pg_textsearch: Rank PostgreSQL Search Results with BM25
pg_textsearch is a PostgreSQL extension for BM25 relevance-ranked full-text search, with Block-Max WAND for fast top-k queries. It fits teams that want ranked text search inside PostgreSQL, using its text search configurations and indexes.

Key differences
- paradedb supports full-text, vector, and hybrid search plus aggregations; pg_textsearch focuses on BM25-ranked full-text search.
- paradedb is implemented in Rust and integrates Tantivy and Apache DataFusion; pg_textsearch is implemented in C.
- paradedb uses the AGPL-3.0 license for its community edition, with a commercially licensed Enterprise offering; pg_textsearch uses the PostgreSQL license.
- pg_textsearch requires PostgreSQL 17 or 18 and server preloading followed by a restart; paradedb requires a PostgreSQL environment compatible with its extension deployment requirements.
- pg_textsearch supports BM25 indexes on expressions, partial indexes, and partitioned tables, while paradedb emphasizes search alongside PostgreSQL filters, joins, facets, and metrics.
- The supplied project figures list 9.3k stars and 471 forks for paradedb, compared with 4k stars and 122 forks for pg_textsearch.
Choose paradedb if you…
- need vector or hybrid retrieval alongside full-text search in PostgreSQL.
- want search filters, joins, facets, and analytics over PostgreSQL data.
- prefer SQL and PostgreSQL transactions for search and analytical queries in one database.
Choose pg_textsearch if you…
- need BM25-ranked text search with PostgreSQL text search configurations and SQL workflows.
- want expression, partial, or partitioned-table BM25 indexes, or parallel index builds.
- can meet its PostgreSQL version and server-preloading requirements and want controls for compaction and memory behavior.
