Kind people,
Here's something I came up with for finding whether a PostgreSQL 7.4
user is in a group.
Cheers,
D
CREATE OR REPLACE FUNCTION in_group (text, text) RETURNS BOOLEAN AS '
DECLARE
the_user ALIAS FOR $1;
the_group ALIAS FOR $2;
dummy text; -- SELECT INTO dummy because PERFORM always returns true.
-- Is this a bug?
BEGIN
SELECT INTO dummy u.usename
FROM
pg_user u
, pg_group g
WHERE
u.usename = the_user
AND g.groname = the_group
AND u.usesysid = ANY (g.grolist);
IF FOUND
THEN
RETURN true;
ELSE
RETURN false;
END IF;
END;
' LANGUAGE 'plpgsql' STRICT IMMUTABLE;
