^The usual [INSERT], [UPDATE], and [DELETE] commands work on an R*Tree
index just like on regular tables.  ^(So to insert some data into our sample
R*Tree index, we can do something like this:
</p>

<blockquote><pre>
INSERT INTO demo_index VALUES(
    1,                   -- Primary key
    -80.7749, -80.7747,  -- Longitude range
    33.3776, 35.3778     -- Latitude range
);
INSERT INTO demo_index VALUES(
    2,
    -81.0, -79.6,
    35.0, 36.2
);
</pre></blockquote>)^
