ALTER OPERATOR CLASS

ALTER OPERATOR CLASS—更改运算符类的定义

ALTER OPERATOR CLASS — change the definition of an operator class

Synopsis

ALTER OPERATOR CLASS name USING index_method
    RENAME TO new_name

ALTER OPERATOR CLASS name USING index_method
    OWNER TO { new_owner | CURRENT_ROLE | CURRENT_USER | SESSION_USER }

ALTER OPERATOR CLASS name USING index_method
    SET SCHEMA new_schema

Description

ALTER OPERATOR CLASS 更改运算符类的定义。

ALTER OPERATOR CLASS changes the definition of an operator class.

您必须拥有该运算符类才能使用 ALTER OPERATOR CLASS 。若要更改所有者，您必须能够对新的所有者角色执行 SET ROLE 操作，并且该角色必须在运算符类的架构上具有 CREATE 权限。（这些限制强制执行更改所有权操作的操作与您通过删除和重新创建运算符类所能执行的操作相同。不过，超级用户无论如何都可以更改任何运算符类的所有权。）

You must own the operator class to use ALTER OPERATOR CLASS. To alter the owner, you must be able to SET ROLE to the new owning role, and that role must have CREATE privilege on the operator class’s schema. (These restrictions enforce that altering the owner doesn’t do anything you couldn’t do by dropping and recreating the operator class. However, a superuser can alter ownership of any operator class anyway.)

Parameters

  • name

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

  • index_method

    • The name of the index method this operator class is for.

  • new_name

    • The new name of the operator class.

  • new_owner

    • The new owner of the operator class.

  • new_schema

    • The new schema for the operator class.
