Well, from 7.4 you can do:

INSERT INTO test SELECT ARRAY[textvalue1, textvalue2] FROM test2;
INSERT 0 2
richardh=> SELECT * FROM test;
details
-----------------
{Hello1,World1}
{hello2,World2}
(2 rows)

I think in 7.3 you might have to write your own function to assemble the
array. I'm not an array expert though, so might be worth checking the
mailing list archives.
