Try the latest development driver from jdbc.postgresql.org. That version
should handle queries that return multiple resultsets correctly. This
was added in build 303. It hasn't had huge amounts of testing, though,

Yeah, this isn't ever going to work, the JDBC spec requires the driver
to complain if you give a SELECT-style query to addBatch() (and how
would you get the results, anyway?)
