Subject: handle connection failure error



doubt in Postgres module in ruby .

 using PGConn i connect with database . Then I executed one query .


def executeSql
         query1= "select * from user_info ;

         begin
           obj.query( query1 )

         rescue PGError => e

         end



end

My problem is that , if there is  a query error , i will rescue that
error and i go ahead . But if there is a connection error , i want to
exit the process . How do  i find out whether it is a connection error
and query error . Is there any Exception handling for connection error
in ruyu

Thanks
