Ctalk 0.0.32a (Default branch)
Ctalk provides object oriented programming features, like classes, methods, operator overloading, and inheritance to otherwise standard C programs. You can use only a few objects and classes in a program, or you can write programs entirely in Ctalk. The package provides a translator from Ctalk source code into C for compilation and a library that provides run-time support for class objects. The preprocessor, ctpp, is also available separately, and the package includes sample programs and documentation. License: GNU General Public License (GPL) Changes:
This release adds improvements in class variable expression analysis and contains several bugfixes.Image

drop_operator_family

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.
