NAME

       DROP OPERATOR CLASS - remove an operator class

SYNOPSIS

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

DESCRIPTION

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

       DROP OPERATOR CLASS does not drop any of the operators  or  functions  referenced  by  the
       class.  If there are any indexes depending on the operator class, you will need to specify
       CASCADE for the drop to complete.

PARAMETERS

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

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

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

       CASCADE
              Automatically drop objects that depend on the operator class.

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

NOTES

       DROP OPERATOR CLASS will not drop the operator family containing the class, even if  there
       is  nothing  else  left  in  the  family  (in particular, in the case where the family was
       implicitly created by CREATE OPERATOR CLASS). An empty operator family  is  harmless,  but
       for the sake of tidiness you might wish to remove the family with DROP OPERATOR FAMILY; or
       perhaps better, use DROP OPERATOR FAMILY in the first place.

EXAMPLES

       Remove the B-tree operator class widget_ops:

       DROP OPERATOR CLASS widget_ops USING btree;

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

COMPATIBILITY

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