Do they show up in a client? For example psql:

test_(aklaver)> create or replace function TestWithBasicTypeArguments( i
int, n numeric, t text)
returns integer
as $$

begin

raise log 'Test.TestWithArguments: i = %, n = %, t = %', i, n, t;

return 0;

end;

CREATE FUNCTION

test_(aklaver)> set client_min_messages = 'debug1';

test_(aklaver)> select testwithbasictypearguments(1, 2.5, 'test');
LOG: Test.TestWithArguments: i = 1, n = 2.5, t = test
testwithbasictypearguments
