That's interesting.  The JDBC driver uses protocol features that aren't
used by psql, so it's possible that the leak is triggered by one of
those features.  I wouldn't worry too much about duplicating the problem
from psql anyway --- a Java test case will do fine.

Even if that works around it for you, please pursue getting a test case
together so we can find and fix the underlying problem.
