Postgres 8.1.2, Java, JDO, and case sensitivity woes

[Matthew Hixson <hixson@xxxxxxxxxxxxxxxx>]

I'm trying to get a large Java application which makes use of an  
Oracle JDO layer to work with Postgres.  Set aside for a moment the  
discussion of whether or not that is going to work.
  What I have found is that different parts of this application are  
referring to a table in all uppercase and in other parts referring to  
the table all in lowercase.  Is there a way to configure Postgres so  
that it does not treat "FOO" and "foo" as two different tables?
  Thanks,
