Description
Use the DROP OPERATOR command to remove an existing operator from the database. You can only drop an operator if you are the operator's owner or a superuser.
Warning
Removing an operator when there are access methods or operator classes that rely on it can cause problems; be sure you know what elements of your database rely on an operator before dropping it.
Example
The following example drops the binary !# operator for the integer data types:
booktown=# DROP OPERATOR !# (integer, integer);
DROP
