Most likely you need a driver and the JDBC Socket Factory to get it to work properly. You should bundle the postgres connector with the socket factory into a uber-jar and see if that solves the problem.

Here is a quick (untested) pom that should accomplish this:

   4.0.0
   com.example
   postgres-with-cloud-sql-socket-factory
   pom
   0.0.1

   
      
         org.postgresql
         postgresql
         42.2.5
      
      
         com.google.cloud.sql
         postgres-socket-factory
         1.0.13
      
   

   
      
         
            org.apache.maven.plugins
            maven-assembly-plugin
            2.4.1
            
               
               
                  jar-with-dependencies
               
            
            
               
                  make-assembly
                  
                  package
