Hello!
I have table like
CREATE TABLE stats
(
username varchar(256) NOT NULL,
"time" int8 NOT NULL,
duration int4 NOT NULL,
phonenumber varchar(20) NOT NULL,
and so on ...
)
I have function like
CREATE OR REPLACE FUNCTION auth("varchar", "varchar")
RETURNS bool AS '
...
' LANGUAGE 'plperlu' VOLATILE;
where first argument is username and second is password. This function
returns true if username and password validated successfully or false
otherwise.
I have a user which must do only selects from table "stats".
My questions is how to restrict access on table "stats" to this user in
way where this user will be able to select only limited set of columns
from table "stats" and only rows with usernames for which this user
knows correct passwords validated via auth() function call.
Any help will be appreciated.
