I meant to say too that in pl/pgsql, you can use argument names directly
(unless you're using a *really* old version of PostgreSQL), making your
code easier to read:
create function user_checkCredentials(username character varying)
returns character varying as
$$
declare
permission character varying;
begin
select into permission permtype from users
where uid = username;
return permtype;
end
$$
language plpgsql;
I'd also use "character varying" for "permtype"; there's no need to use
a record as you're only only getting a single column.
