Changes the definition of an operator class.

ALTER OPERATOR CLASS changes the definition of an operator class.
You must own the operator class to use
ALTER OPERATOR CLASS. To alter the owner, you must also be a direct or indirect member of the new owning role, and that role must have
CREATE privilege on the operator class’s schema. (These restrictions enforce that altering the owner does not do anything you could not do by dropping and recreating the operator class. However, a superuser can alter ownership of any operator class anyway.)
The name (optionally schema-qualified) of an existing operator class.
The name of the index method this operator class is for.
The new name of the operator class.
The new owner of the operator class
There is no
ALTER OPERATOR statement in the SQL standard.
