Interesting. On 8.3.5 I tried
CREATE TABLE mytable (
id serial NOT NULL,
mytable int NOT NULL,
PRIMARY KEY (id)
);
INSERT INTO mytable VALUES
(1, 10),
(2, 20),
(3, 30),
(4, 40),
(5, 50),
(6, 60);
SELECT array(SELECT mytable FROM mytable);
and it returned
{10,20,30,40,50,60}
Only when I renamed the second column from "mytable" to "mytablex" I got
{"(1,10)","(2,20)","(3,30)","(4,40)","(5,50)","(6,60)"}
as you promised. Is there any syntax for treating the first "mytable"
as a composite type name instead of a column name?
