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 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.)
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.
The new schema for the operator class.
