Short version:
How can I do batch select queries with jdbc-postgresql?

Long version:
I'm migrating a transaction management system from Oracle to

We use batch select queries quite a bit, and to accomplish this in
Oracle we just separated the queries with "\n" and ran:

Doing this in PostgreSQL (with a semicolon as a delimeter) generates
this error:
Cannot handle multiple result groups.

So then I figured it wasn't supported and looked up the 'executeBatch'
function, but now that leads me to this problem:

This works:
stmt.executeQuery("select * from pay_methods");

But this doesn't:
stmt.addBatch("select * from pay_methods");

The following error is output:
Batch entry 0 .... Call getNextException() to see the cause. calling
getNextException() produces this:
A result was returned when none was expected.

Please advise me on how to accomplish batch select queries.

Thanks for the help,
