tables permissions once again

Hi

Yeach ... I can revoke from public now ;), but .....
look at this:
#create database a
CREATE

#\c a
#create table ala(a int4);
CREATE

#\z
Access permissions for database "a"
Relation | Access permissions
----------+--------------------
ala |
(1 row)

#revoke all on ala from public;
CHANGE
#\z
Access permissions for database "a"
Relation | Access permissions
----------+-----------------------
ala | {"=","postgres=arwR"}
(1 row)

hmmm.... is everything work ok ?
