means of an index, the above command will also create an index with the same
name as the constraint. If you later on change the name of one of those, the
name of the corresponding object will be changed automatically as well.

Indexes are also used internally by constraints, namely by UNIQUE and
PRIMARY KEY constraints. If you rename an index that is used internally by
a constraint of that type, this constraint will implicitly be renamed as
well. On the other hand, if you rename such a constraint, it will
implicitly rename its corresponding index such that both objects always
have the same name.

There was formerly an <command>ALTER INDEX OWNER</> variant, but
this is now ignored (with a warning). An index cannot have an owner
