inserting custom type array into table column in postgresql-9.4?

Question

I have a custom type "nameage" and a table "namesages".

CREATE TYPE nameage AS(
name_ varchar(50),
age smallint 
);
CREATE TABLE namesages(
id serial,
namesandages nameage[]
);

INSERT INTO namesages(namesandages) VALUES(ARRAY[['john', 24],['david', 38]]::nameage[]);

Why does this query give error?;

ERROR:  malformed record literal: "john"
LINE 1: insert into namesages(namesandages) values(ARRAY[['john', 24...
                                                          ^

Answer 1

What you meant to do was this:

INSERT INTO namesages(namesandages) 
VALUES(ARRAY[ROW('john', 24),ROW('david', 38)]::nameage[]);

This creates a one dimensional array of user-defined composite types. I'm not sure what you intended to do when you defined a two-dimensional array...
