My first revoke - Mailing list pgsql-general

So I have created a role

create role my_role   with NOSUPERUSER NOCREATEDB NOCREATEROLE  LOGIN
ENCRYPTED PASSWORD 'secret';

Now I wish to grant only select for this role on some tables.

So I do

revoke all privileges on table  X  from my_role;

and i do this for all my tables (X is table name) ?

and then

grant select on table X to my_role;

for all tables?
