I have redirected the question to the JDBC list.

What does your code look like?

The documentation
(https://jdbc.postgresql.org/documentation/head/load.html)
has it:

  Prior to Java 1.6, the driver had to be loaded by the application - either by calling

  Class.forName("org.postgresql.Driver");

  or by passing the driver class name as a JVM parameter.

  java -Djdbc.drivers=org.postgresql.Driver example.ImageViewer

  These older methods of loading the driver are still supported but they are no longer necessary.

I do it all the time, and it works just fine.

Just use "org.postgresql.Driver" as the driver class name and make
sure the JAR file is on your class path.
