## ✨ Release highlights

###
### Full PostgreSQL 18 support

Building on the PostgreSQL 18 support introduced in PMM 3.5.0, we've now added enhanced Query Analytics (QAN) metrics for WAL buffer usage and parallel worker statistics. You can access these metrics via the QAN API (GetReport and GetFilter endpoints). To explore these endpoints, see your PMM Server's Swagger UI at /swagger/. UI support is planned for a future release.

For setup instructions, see [Connect PostgreSQL databases to PMM](../install-pmm/install-pmm-client/connect-database/postgresql.md).
