Please help me .
this code :
  ResultSet fksRS = dbmd.getImportedKeys(null, null, tableName);
    while(fksRS.next())
    {
        ... fksRS.getString("FKCOLUMN_NAME");
    }
  
I get a NullPointerException because fksRS is null, but I don't know
why. This is not the case when I use MS SQL Server...it does work. Is
this because the JDBC driver provided with PostgreSQL doesn't support
this function?

You shouldn't be getting a NullPointerException here.  Could you send a
complete example that generates this error?
