Syntax diagrams

Read left to right. Branches are choices, bypasses are optional, loops repeat. Select an underlined parameter to open its rule.

DROP OPERATOR drops an existing operator from the database system. To execute this command you must be the owner of the operator.

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 NONE if the operator has no left operand.
right_type: The data type of the operator's 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 5.15).
RESTRICT: Refuse to drop the operator if any objects depend on it. This is the default.

Remove the power operator a^b for type integer:

DROP OPERATOR ^ (integer, integer);

Remove the bitwise-complement prefix operator ~b for type bit:

DROP OPERATOR ~ (none, bit);

Remove multiple operators in one command:

DROP OPERATOR ~ (none, bit), ^ (integer, integer);

There is no DROP OPERATOR statement in the SQL standard.
