| <command>ALTER OPERATOR CLASS</command> changes the definition of |
| an operator class. |
| </para> |
| |
| <para> |
| You must own the operator class to use <command>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 <literal>CREATE</literal> 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.) |
