Ok.. the problem is that your resultset has no metadata attached.. (it's 
null)  Notice "ResultSetMetaData.getColumnCount(...)"

I have never used this syntax.. (row.getObject(..)) so I'm not familiar 
with what it returns. I would research this first.. It could be a jdbc 
implementation issue.. (contact Postgresql folks.. maybe..??)
