The PostgreSQL implementation of the R2DBC SPI, providing a reactive, non-blocking driver for PostgreSQL on the JVM. It supports SCRAM/MD5 authentication, TLS, Unix domain sockets, fail-over, notifications, logical decoding, and prepared statements with bindings.

Use cases

• connect to postgresql reactively from java
• non-blocking database access in spring webflux
• reactive sql queries with project reactor
• listen to postgresql notifications reactively
• consume logical replication streams from postgres
• connect over unix domain socket to postgres
• multi-host connection fail-over for postgres

When to choose

• you need reactive/non-blocking PostgreSQL access on the JVM
• you use Spring Data R2DBC or another R2DBC client
• you need LISTEN/NOTIFY or logical decoding in a reactive pipeline

When to avoid

• you use blocking JDBC or traditional servlet stacks
• you use a database other than PostgreSQL
• you want a higher-level ORM rather than a driver
