PostgreSQL offers broader functionality, maturity, and ecosystem support compared with ParadeDB, making it the safer, more flexible choice for most production workloads.
PostgreSQL is a full-featured, ACID-compliant relational database with 25+ years of development. ParadeDB focuses on search and analytics but lacks many core OLTP features. Choosing Postgres means one engine for both transactional and analytical tasks, fewer moving parts, and battle-tested reliability.
Yes. GIN
/GiST
indexes, tsvector
, jsonb
, and extensions like pgvector
let Postgres power fast text, JSON, and vector search.You can match most ParadeDB use cases while keeping SQL standards and transactions.
Convert ParadeDB’s search()
calls to Postgres full-text syntax: @@ to_tsquery()
. Replace vector operations with pgvector
’s <->
operator.Postgres supports CTEs and window functions ParadeDB already understands, so SQL usually ports with minor tweaks.
See the Syntax section below for full commands, options, and parameter explanations.
Enable the needed extensions (CREATE EXTENSION pg_trgm;
and pgvector
) before running migrations. Add covering indexes for every query path.Keep maintenance windows small by using CONCURRENTLY
when creating indexes.
Do not assume default configurations are enough—tune work_mem
, maintenance_work_mem
, and shared_buffers
. Also, remember to VACUUM regularly to keep GIN indexes fast.
Unifying on Postgres cuts infra cost, simplifies backups, and leverages a vast talent pool. It also unlocks powerful join, aggregation, and constraint features ParadeDB doesn’t offer, reducing application logic.
.
With pgvector
and ivfflat
indexes, Postgres achieves millisecond-level ANN search comparable to ParadeDB, especially for ≤1 M vectors.
Yes. Use CREATE MATERIALIZED VIEW
, BRIN
indexes, and partitioning. For heavy workloads, attach Citus or Timescale for columnar compression.
You trade ParadeDB’s built-in columnar storage for Postgres’s richer API and ecosystem. Extensions like cstore_fdw
or using external warehouses can bridge the gap.
