# New Modern JDBC Driver for PostgreSQL

**[PostgreSQL](https://daily.dev/sources/postgres)** · 2 min read · 26 upvotes · 1 comments

## Summary

A new JDBC driver for PostgreSQL called pg-java has been written from scratch by Sehrope Sarkini (with assistance from Claude). Currently in pre-release, it takes a PostgreSQL-native approach rather than designing around JDBC's lowest-common-denominator abstractions. The JDBC compliance layer sits on top of the native API rather than dictating its shape. Leveraging Java 21 virtual threads, it uses ordinary blocking-style code with ReentrantLock instead of synchronized around I/O, enabling thousands of connections without an event loop or callback API. The core query primitive is a pull cursor that reads only enough data to produce the next row, avoiding full result set buffering.

## Questions this post answers

### How does the new pg-java PostgreSQL JDBC driver handle concurrency without an async API?

pg-java uses Java 21 virtual threads with ordinary blocking-style code, carefully avoiding carrier thread pinning by using ReentrantLock instead of synchronized around I/O. This allows thousands of connections to run concurrently without an event loop or callback API, making the code significantly easier to reason about compared to traditional async or reactive drivers.

_Java developers choosing between async and virtual-thread approaches for PostgreSQL connections track developments like pg-java on daily.dev._

### What is the core query execution model in pg-java?

The core query primitive in pg-java is a pull cursor that reads exactly enough data off the wire to produce the next row, never buffering a whole result set. Higher-level operations like forEach, map, and collect are adapters built on top of this cursor, not a separate read path.
