Hi

I am using 7.0.2, here is and example.

Acct-Session-Time is int4
Acct-Delay-Time is int4

select "Acct-Session-Time" || ',' || "Acct-Delay-Time" as
compound_numbers from febstop limit 2;
compound_numbers
-----------------
1137,0
2083,0
(2 rows)

I also tried :

select "Acct-Session-Time"::text || ',' || "Acct-Delay-Time"::text as
compound_numbers from febstop limit 2;
compound_numbers
-----------------
1137,0
2083,0
(2 rows)

This is pretty simple but it works for me.
