PgJDBC is the official open-source PostgreSQL JDBC driver, written in pure Java (Type 4) and communicating via the PostgreSQL native network protocol. It lets Java programs connect to and query PostgreSQL databases using standard, database-independent JDBC code, with support for SSL, SCRAM authentication, connection pooling, and PostgreSQL-specific extensions.

Use cases

• connect a Java application to a PostgreSQL database
• run SQL queries and process result sets from Java
• use PostgreSQL with JDBC-based ORMs like Hibernate
• configure SSL and SCRAM channel-binding for secure database connections
• call PostgreSQL stored procedures and functions from Java
• store and retrieve binary data (bytea, large objects) in PostgreSQL
• use PostgreSQL in a servlet or multithreaded Java server environment

When to choose

• your Java or JVM application needs to talk to PostgreSQL
• you want a pure-Java, platform-independent driver with no native dependencies
• you need full JDBC 4.2 compliance plus PostgreSQL-specific features like jsonb, arrays, and replication
• you need a mature, actively maintained driver with regular security fixes

When to avoid

• you are connecting to a database other than PostgreSQL
• you need a non-JVM language driver (use libpq, psycopg, node-postgres, etc.)
• you require reactive/R2DBC access instead of blocking JDBC
