Here's a simple function I've used so I can do it in the database.
Written with help from this very list ;-)
CREATE OR REPLACE FUNCTION gen_password() RETURNS text AS $$
DECLARE
password text;
chars text;
BEGIN
password := '';
chars :=
'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
FOR i IN 1..8 LOOP
password := password || SUBSTRING(chars,
ceil(random()*LENGTH(chars))::integer, 1);
END LOOP;
return password;
END;
$$
LANGUAGE plpgsql;
Then you can do stuff like:
update people set pp_password = gen_password() where pp_password is null;
