When building high-performance Node.js applications with PostgreSQL, choosing the right driver can have a noticeable impact on query latency and throughput. To compare the most popular options, we ran a benchmark using mitata to test four approaches:
- pg-native brianc/node-postgres (C library bindings)
- pg brianc/node-postgres (standard JavaScript implementation)
- postgres.js porsager/postgres (standard JavaScript implementation)
- postgres.js porsager/postgres (unsafe mode used by some wrappers)

1.12x faster than porsager/postgres (postgres)
1.19x faster than porsager/postgres (unsafe)
pg-native Wins
The pg-native driver leverages libpq, the official PostgreSQL C client library. This allows faster query parsing, lower overhead on network I/O, and better memory handling than the pure JavaScript implementation (pg). Essentially, pg-native skips part of the JS-to-database abstraction cost.
pg Is Close Behind
Despite being pure JavaScript, pg remains very efficient and stable. The performance gap (~6%) is small and might not be noticeable in real-world apps unless you're processing tens of thousands of queries per second.
Conclusion
For high-throughput Node.js applications where microseconds matter, pg-native consistently outperforms both pg and postgres.js. However, the difference isn’t massive — your choice should balance performance, API design, and operational complexity.
