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

       CREATE_OPERATOR_FAMILY - define a new operator family

SYNOPSIS

       CREATE OPERATOR FAMILY name USING index_method

DESCRIPTION

       CREATE OPERATOR FAMILY creates a new operator family. An operator family defines a collection of related operator classes, and perhaps some
       additional operators and support functions that are compatible with these operator classes but not essential for the functioning of any
       individual index. (Operators and functions that are essential to indexes should be grouped within the relevant operator class, rather than
       being "loose" in the operator family. Typically, single-data-type operators are bound to operator classes, while cross-data-type operators
       can be loose in an operator family containing operator classes for both data types.)

       The new operator family is initially empty. It should be populated by issuing subsequent CREATE OPERATOR CLASS commands to add contained
       operator classes, and optionally ALTER OPERATOR FAMILY commands to add "loose" operators and their corresponding support functions.

       If a schema name is given then the operator family is created in the specified schema. Otherwise it is created in the current schema. Two
       operator families in the same schema can have the same name only if they are for different index methods.

       The user who defines an operator family becomes its owner. Presently, the creating user must be a superuser. (This restriction is made
       because an erroneous operator family definition could confuse or even crash the server.)

       Refer to Section 35.14, "Interfacing Extensions To Indexes", in the documentation for further information.

PARAMETERS

       name
	   The name of the operator family to be created. The name can be schema-qualified.

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

COMPATIBILITY

       CREATE OPERATOR FAMILY is a PostgreSQL extension. There is no CREATE OPERATOR FAMILY statement in the SQL standard.
