Do not throw an error if the operator does not exist. A notice is issued in this case.
The name (optionally schema-qualified) of an existing operator.
The data type of the operator's left operand; write
NONEif the operator has no left operand.

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).
Refuse to drop the operator if any objects depend on it. This is the default.
