pg_user, changing priviliges

From

I'm trying to give a createuser privilige by changing pg_users, i'm logged
in as a superuser.

mtldb=# select count(*) from pg_user  where usename='mtluser';
 count
-------
     1
(1 row)

mtldb=# update pg_user set usesuper=true, usecatupd=true where
usename='mtluser';
UPDATE 0

Why I can't do it?

reedstrm=> \d pg_user
View    = pg_user

Because pg_user is a view on pg_shadow. Can't update a view. The right
way to go about adding createuser privilage to a user is:

ALTER USER foouser CREATEUSER;

You need to change pg_shadow.

 pg_user is a view; you should be updating pg_shadow
