Description
   
    DROP OPERATOR
   
   drops an existing operator from
   the database system.  To execute this command you must be the owner
   of the operator.
  
Parameters
- 
     
      IF EXISTS
- 
     Do not throw an error if the operator does not exist. A notice is issued in this case. 
- 
     
      
       name
- 
     The name (optionally schema-qualified) of an existing operator. 
- 
     
      
       left_type
- 
     The data type of the operator's left operand; write NONEif the operator has no left operand.
- 
     
      
       right_type
- 
     The data type of the operator's right operand; write NONEif the operator has no right operand.
- 
     
      CASCADE
- 
     Automatically drop objects that depend on the operator (such as views using it), and in turn all objects that depend on those objects (see Section 5.14 ). 
- 
     
      RESTRICT
- 
     Refuse to drop the operator if any objects depend on it. This is the default.
