It's a psql interactive thing rather than something you can use from
other clients:
   \set on_error_rollback
It's designed to help with spelling mistakes/scripts etc.

If you get an error back from an insert you need to catch it and
rollback yourself.

Of course by default, all PostgreSQL statements execute in their own
transaction. That would mean your SELECT would be fine, and implies
something in your JDBC setup is issuing "BEGIN" without your knowledge.
