Perfect, worked like a charm ... but the RETURNS still needs to be a SETOF, other then that, I'm 'away to the races' ... thanks :)

Hi Marc,
One option is to create a simple data type and return the rowtype of the datatype
eg CREATE TYPE tserverload AS ("server_name" text, "load_avg" int4);
CREATE FUNCTION getserverload()
RETURNS tserverload
AS
'DECLARE
r tserverload%rowtype;
etc.
You would then return r, comprised of r.server_name and r.load_avg.

Subject: [SQL] PL/PgSQL - returning multiple columns ...
I have a function that I want to return 'server_name, avg(load_avg)' ... if I wanted to return matching rows in a table, I can do a 'setof <table>', with a for loop inside ... but what do I set the 'RETURNS' to if I want to return the results of query that returns only two fields of a table, or, in the case of the above, one column and oen 'group by' column?
thanks ...
