regarding grant option

hi all....
this is akhilesh from india.i just want to ask one thing regarding grant
operation??
i am using pgsql 8.0 on ubuntu 5.10 linux.
just tell me the procedure that how can i grant all permissions for a
database to any of the other user???
i am using :-
:->> grant all privileges on database <db_name> to <user_name>;
GRANT
:->> grant all ON DATABASE <db_name> to <user_name>;
GRANT

and the query executes succesfully.
but at the other user end, she is not able to access the database given in
the above query.
here i have to grant permissions to that user individually for each and
every table by using:
:->> grant ALL ON <tab_name> to <user_name>;
GRANT

and all the permissions are granted to that user for that particular table.

i want same results for the entire database.................
