I don't believe you can do that.

Thanks that works pretty well. Is it possible to fetch the all the
return of dates_pkg.getbusinessdays() into a single variable at once?
i.e. in Oracle I would do something like
CRATE table_type as TABLE of TYPE record_type;
declare
allrows table_type;
BEGIN
allrows := dates_pkg.getbusinessdays();
END;
And allrows would be a collection that I can iterate over at my
leisure. I have to problem writing future code to just do a for loop
over the select, but while migrating existing code I'd rather keep it
as intact as possible.
1) If you declare a return type setof TABLENAME the resultset
willcontain 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
withfunctions that return SETOF datatype. In Oracle, the functions
I'mporting return a TABLE of TYPE datatype, this TABLE being itself
anamed type. I am not aware of how to do this in PLPGSQL.
Consider a function with header:
CREATE OR REPLACE FUNCTIONdates_pkg.getbusinessdays(pstartdate
timestamp with time zone,penddate timestamp with time zone) RETURNS
SETOF timestamp with timezone 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
anotherplpgsql function. Any hints?
