least() and greatest() have some type unification logic that I don't
think works for actual functions.
create function s(variadic anyarray) returns anyelement
language sql immutable
as $$ select min(v) from unnest($1) u(v); $$;
select s(1,2,3); -- works
select s(1,2,3.0); -- ERROR: function s(integer, integer, numeric) does not exist
select least(1,2,3.0); -- works
