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.
