About retrieving objects' priviledge info such as grantee & its privileges for a specific object (view, table, function, etc.)

[Ying Lu <ying_lu@xxxxxxxxxxxxxxx>]

Hello,

May I know the commands to retrieve objects' privileges info please? 
Something like:


Object Type, Object name,    creator,    grantee,    privilege,        
is_creatable
===================================================================
table      T1        user1     user2     select, update, delete        no
table      T1        user1     user3      
select                                 no
view       V1       user2      user4     
select                                 no

P.S. (postgreSQL 8.0.1)

Thanks a lot,
Emi
