21 ALTER OPERATOR changes the definition of an operator.
22
23 You must own the operator to use ALTER OPERATOR. To alter the owner,
24 you must be able to SET ROLE to the new owning role, and that role must
25 have CREATE privilege on the operator's schema. (These restrictions
26 enforce that altering the owner doesn't do anything you couldn't do by
27 dropping and recreating the operator. However, a superuser can alter
28 ownership of any operator anyway.)
29
31 name
32 The name (optionally schema-qualified) of an existing operator.
33
34 left_type
35 The data type of the operator's left operand; write NONE if the
36 operator has no left operand.
37
38 right_type
39 The data type of the operator's right operand.
40
41 new_owner
42 The new owner of the operator.
43
44 new_schema
45 The new schema for the operator.
46
47 res_proc
48 The restriction selectivity estimator function for this operator;
49 write NONE to remove existing selectivity estimator.
50
51 join_proc
52 The join selectivity estimator function for this operator; write
53 NONE to remove existing selectivity estimator.
54
56 Change the owner of a custom operator a @@ b for type text:
57
58 ALTER OPERATOR @@ (text, text) OWNER TO joe;
59
60 Change the restriction and join selectivity estimator functions of a
61 custom operator a && b for type int[]:
62
63 ALTER OPERATOR && (_int4, _int4) SET (RESTRICT = _int_contsel, JOIN = _int_contjoinsel);
64
66 There is no ALTER OPERATOR statement in the SQL standard.
