Duplicate key identification

              Hello all !

        I have the following problem : I work on a Java database
backup/restore tool which should work with some different database
engines like Oracle , AdabasD and PostgreSQL using JDBC.My problem is a
way to identify the 'Duplicate key ' error for all these database
engines.For AdabasD and Oracle is can be done using the getErrorCode()
method but not for PostgreSQL. Right now I'm using not a very nice way :
searching in the error message.Does anybody knows other better solution
? Error messages in PostgreSQL are language dependent ?

Thanks in advance ,

Crosby.
