All right. I found the function.

Thanks a lot!

Thanks a lot! I just noticed that my postgresql is 8.3(unnest function
is not there by default). Is there a way that I could download and load
only this function from somewhere?
Thanks again!

Hello,
Is there a function to split a string to different rows?
For example, t1(id, col1)
values(1, 'a, b, c');
select id, string_split_to_row(col1, ',');
Return:
=========
1, a
1, b
1, c
You can probably use some combination of "string_to_array" and "unnest"
e.g.
SELECT unnest(string_to_array('a,b,c', ','));
unnest
--------
a
b
c
(3 rows)
If you need a more complex string splitting mechanism, there is the
"regexp_split_to_array" function.
