i hate $1, $2 personally.. they make my eyes cross eventually (esp. once you
have 3 or 4 params.. ick) and they are hard to maintain in larger functions
(what was that $2 param again???)
so i usually use pl/pgsql and do this:
CREATE FUNCTION fn_fubar(int4) returns int4 AS '
DECLARE
myParam alias for $1;
BEGIN
UPDATE foo SET bar = tmp.numb FROM tmp WHERE tmp.numb = myParam;
return myParam;
END; '
LANGUAGSE 'pl/pgsql';
more typing, but easier to read and maintain later... but then, i'm picky.
