1) If you declare a return type setof TABLENAME the resultset will
contain rows with field definitions like the table.
2) To call the function from another plpgsql function use:
declare
row record
begin
for row in select * from dates_pkg.getbusinessdays(...) Loop
...process...
end loop
...
end

I am porting some Oracle code to PLPGSQL and am having a problem with
functions that return SETOF datatype. In Oracle, the functions I'm
porting return a TABLE of TYPE datatype, this TABLE being itself a
named type. I am not aware of how to do this in PLPGSQL.
Consider a function with header:
CREATE OR REPLACE FUNCTION
dates_pkg.getbusinessdays(pstartdate timestamp with time zone,
penddate timestamp with time zone) RETURNS SETOF timestamp with time
zone AS
I can easily call this function in SQL like so:
select * from dates_pkg.getbusinessdays( now(), now()
+ INTERVAL '7' day ) as business_day;
However, I can't figure out how to call this function from another
plpgsql function. Any hints?
