16

PARAMETERS

18       IF EXISTS
19              Do not throw an error if the operator class does  not  exist.  A
20              notice is issued in this case.
21
22       name   The  name  (optionally schema-qualified) of an existing operator
23              class.
24
25       index_method
26              The name of the index access method the operator class is for.
27
28       CASCADE
29              Automatically drop objects that depend on the operator class.
30
31       RESTRICT
32              Refuse to drop the operator class if any objects depend  on  it.
33              This is the default.

EXAMPLES

36       Remove the B-tree operator class widget_ops:
37
38       DROP OPERATOR CLASS widget_ops USING btree;
39
40       This  command  will  not succeed if there are any existing indexes that
41       use the operator class. Add CASCADE to drop such indexes along with the
42       operator class.
