Re: How to get DB connection PID from JDBC

Hi Oleg,

Maybe you can use the extensions to the JDBC API:

        try (Connection conn =
DriverManager.getConnection(getJdbcUrl(), getUsername(),
getPassword())) {
            PGConnection pgconn =
conn.unwrap(org.postgresql.PGConnection.class);
            System.out.println(pgconn.getBackendPID());
        }

Regards,
