I started with this issue on the pgsql-jdbc list, but was assured that this
could not be a bug in the JDBC driver -- it is either a bug in the
configuration or runtime environment or it is a server-side bug. This list
seemed like the logical next step.
We have seen this behavior in 8.0.3
files. Is there any chance that the
error/rollback path in the code is leaking open files on the server? Is there
anything I should run during the test to watch for potential resource
exhaustion?

One more thought on the topic -- in the particular case where we hit
this, the Statement did not have any requests active on its connection.
If the driver can determine this, it could return from the cancel method
without doing anything.
