CLASS(7) 				  PostgreSQL 9.2.7 Documentation				   ALTER OPERATOR CLASS(7)

NAME

       ALTER_OPERATOR_CLASS - change the definition of an operator class

SYNOPSIS

       ALTER OPERATOR CLASS name USING index_method RENAME TO new_name
       ALTER OPERATOR CLASS name USING index_method OWNER TO new_owner
       ALTER OPERATOR CLASS name USING index_method SET SCHEMA new_schema

DESCRIPTION

       ALTER OPERATOR CLASS changes the definition of an operator class.

       You must own the operator class to use ALTER OPERATOR CLASS. To alter the owner, you must also be a direct or indirect member of the new
       owning role, and that role must have CREATE privilege on the operator class's schema. (These restrictions enforce that altering the owner
       doesn't do anything you couldn't do by dropping and recreating the operator class. However, a superuser can alter ownership of any operator
       class anyway.)

PARAMETERS

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

       index_method
	   The name of the index method this operator class is for.

       new_name
	   The new name of the operator class.

       new_owner
	   The new owner of the operator class.

       new_schema
	   The new schema for the operator class.

COMPATIBILITY

       There is no ALTER OPERATOR CLASS statement in the SQL standard.

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.
