DROP OPERATOR 
FAMILY(7) 					   SQL Commands 					   DROP OPERATOR FAMILY(7)

NAME

       DROP OPERATOR FAMILY - remove an operator family

SYNOPSIS

       DROP OPERATOR FAMILY [ IF EXISTS ] name USING index_method [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP OPERATOR FAMILY drops an existing operator family.	To execute this command you must be the owner of the operator family.

       DROP OPERATOR FAMILY includes dropping any operator classes contained in the family, but it does not drop any of the operators or functions
       referenced by the family. If there are any indexes depending on operator classes within the family, you will need to  specify  CASCADE  for
       the drop to complete.

PARAMETERS

       IF EXISTS
	      Do not throw an error if the operator family does not exist.  A notice is issued in this case.

       name   The name (optionally schema-qualified) of an existing operator family.

       index_method
	      The name of the index access method the operator family is for.

       CASCADE
	      Automatically drop objects that depend on the operator family.

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

EXAMPLES

       Remove the B-tree operator family float_ops:

       DROP OPERATOR FAMILY float_ops USING btree;

       This  command  will  not  succeed  if  there are any existing indexes that use operator classes within the family. Add CASCADE to drop such
       indexes along with the operator family.

COMPATIBILITY

       There is no DROP OPERATOR FAMILY statement in the SQL standard.

NAME

       DROP OPERATOR - remove a user-defined operator

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
	      Automatically drop objects that depend on the operator.

       RESTRICT
	      Refuse to drop the operator if there are any dependent objects.  This is the default.

   OUTPUTS
       DROP OPERATOR
	      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
	      This message occurs if the right unary operator specified 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.

       The left or right type of a left or right unary operator, respectively, must be specified as NONE.

   NOTES
       The DROP OPERATOR statement is a PostgreSQL language extension.

       Refer to CREATE OPERATOR [create_operator(7)] for information on how to create operators.

USAGE

       Remove power operator a^n for int4:

       DROP OPERATOR ^ (int4, int4);

       Remove left unary negation operator (! b) for boolean:

       DROP OPERATOR ! (none, bool);

       Remove right unary factorial operator (i !) for int4:

       DROP OPERATOR ! (int4, none);

COMPATIBILITY

   SQL92
       There is no DROP OPERATOR in SQL92.
