Do these tend to perform well? I have some simple formulas in functions like so:
CREATE OR REPLACE FUNCTION public.stat_foo(a integer, b integer, c integer)
RETURNS numeric AS
$BODY$
declare ret numeric;
begin
select (a+b) / c::numeric into ret;
return round(ret, 3);
end
$BODY$
LANGUAGE plpgsql IMMUTABLE COST 100;
The reason I'm doing this is because i repeat this formula in a bunch of views and queries, and it's easier to have one function. Would this somehow be slower than reproducing the formula in every view its used? I'm hoping not...
