So how do I specify an interval in a function?
Works for me:
CREATE FUNCTION
three_hours()
RETURNS interval
STABLE
STRICT
LANGUAGE plpgsql AS $body$
declare
ThreeHours interval;
begin
ThreeHours = interval '3 hours'; -- throws a syntax error
ThreeHours = '3 hours'::interval; -- also throws a syntax error
RETURN ThreeHours;
end
$body$;
CREATE FUNCTION
test=# select three_hours();
three_hours
-------------
03:00:00
(1 row)
test=# select version();
version

I can't tell as you haven't provided a complete example (always
helpful when debugging), but are you sure you're specifying the
correct language type (plpgsql in your case)?
