SYNOPSIS
DROP OPERATOR id ( lefttype | NONE , righttype | NONE ) [ CASCADE | RESTRICT ]
INPUTS
id The identifier (optionally schema-qualified) of an existing operator.
lefttype
The type of the operator's left argument; write NONE if the operator has no left argument.
righttype
The type of the operator's right argument; write NONE if the operator has no right argument.
CASCADE

RESTRICT

The message returned if the command is successful.
ERROR: RemoveOperator: binary operator 'oper' taking 'lefttype' and 'righttype' does not exist
This message occurs if the specified binary operator does not exist.
ERROR: RemoveOperator: left unary operator 'oper' taking 'lefttype' does not exist
This message occurs if the left unary operator specified does not exist.
ERROR: RemoveOperator: right unary operator 'oper' taking 'righttype' does not exist

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