array to rows of it's elements? - Mailing list pgsql-novice

Is there a function which will return the elements of an array as rows of
entries? What I'd like in the 1 dimensional array case is something like:

   select array-to-rows(ARRAY[1,2,3]);

giving

   1
   2
   3
(3 rows)

Thanks,
Celia McInnis
