 <p>HAWQ supports left unary, right unary, and binary operators. Operators can 
be overloaded; that is, the same operator name can be used for different 
operators that have different numbers and types of operands. When a query is 
executed, the system determines the operator to call from the number and types 
of the provided operands.</p>
