Synopsis
DROP OPERATOR [ IF EXISTS ] name ( { left_type | NONE } , right_type ) [, ...] [ CASCADE | RESTRICT ]
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
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 5.14).
RESTRICT
-
Refuse to drop the operator if any objects depend on it. This is the default.
Examples
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);
