Description:

Hi,

It seems that documentation wrong or [ CASCADE | RESTRICT ] feature of ALTER
TYPE ... RENAME TO isn't implemented.

Test case:

create type test as (qqq integer);
CREATE TYPE

alter type test rename to test1 RESTRICT;
ERROR: syntax error at or near "RESTRICT"
LINE 1: alter type test rename to test1 RESTRICT;
^

alter type test rename to test1 CASCADE;
ERROR: syntax error at or near "CASCADE"
LINE 1: alter type test rename to test1 CASCADE;
^

However:
[local]:5432 postgres(at)postgres=# alter type test rename to test1;
ALTER TYPE
