Currently, views are read only: the system will not allow an insert,

update, or delete on a view. You can get the effect of an updatable
133-
view by creating rules that rewrite inserts, etc. on the view into
133+
view by creating <literal>INSTEAD</> triggers on the view, which
134+
must convert attempted inserts, etc. on the view into

appropriate actions on other tables. For more information see

<xref linkend="sql-createtrigger">. Another possibility is to create
137+
rules (see <xref linkend="sql-createrule">), but in practice triggers
138+
are easier to understand and use correctly.
