title: PSQLException: The server does not support SSL
body: <p>Environment</p>
  
  <p>Windows
  HikariCP version: 2.6.0
  JDK version : 1.8.0_65
  Database : PostgreSQL
  Driver version : 42.0.0 org.postgresql</p>
  
  <hr>
  
  <p>It works for some time, like 2 hours, then the exception raises.
  My configuration:</p>
  
  <pre><code>    ds = new HikariDataSource();
      ds.setMaximumPoolSize(poolSize);
      ds.setLeakDetectionThreshold(15000);
      ds.setDataSourceClassName("org.postgresql.ds.PGSimpleDataSource");
      ds.addDataSourceProperty("serverName", serverAddress);
      ds.addDataSourceProperty("databaseName", database);
      ds.addDataSourceProperty("user", user);
      ds.addDataSourceProperty("portNumber", port);
      ds.addDataSourceProperty("password", password);
  </code></pre>
  
  <p>My postgresql.conf is not set nothing related to ssl too.</p>
