Altering array(composite-types) without breaking code when inserting them and similar questions

[Dorian Hoxha <dorian.hoxha@xxxxxxxxx>]

Hi list,

I have a

create type thetype(width integer, height integer);

create table mytable(thetype thetype[]);

How can i make an insert statement so if i later add fields to the composite type, the code/query doesn't break ?
Maybe by specifying the fields of the composite type in the query ?

This can be done for normal inserts(non arrays):

CREATE TABLE mytable (t thetype);

INSERT INTO mytable(t.width, t.height) VALUES (11,22);


Also how to update an whole element of an array of composites ?

Also, how to update an attribute in a specific element in an array of composites?

(so when i add columns later to the composite, my old code doesn't break)

How much overhead have the composite types beside the values and nulls?

Thanks
