"Access privileges" is missing after pg_dumpall

Hi,

I have taken pg_dumpall in pg-master and after restoring the dump I am not able to see the "Access privileges" as below:

Same is reproducible in back branches as well, is this fine ?

CREATE ROLE user1 PASSWORD 'user1' SUPERUSER LOGIN;

CREATE DATABASE db1 OWNER=user1;

GRANT ALL ON DATABASE db1 TO user1;

postgres=# \l+ db1

                                             List of databases

 Name | Owner | Encoding |  Collate      |   Ctype        | Access privileges   |  Size       | Tablespace | Description 

------+-------+----------+------------+------------+-------------------+---------+------------+-------------

 db1    | user1   | UTF8       | en_US.utf8 | en_US.utf8 | =Tc/user1             +| 7621 kB | pg_default  | 

           |             |                 |                    |                    | user1=CTc/user1    |               |                    | 

(1 row)

postgres=# SELECT datname as "Relation", datacl as "Access permissions" FROM pg_database WHERE datname = 'db1';

 Relation |     Access permissions      

----------+-----------------------------

 db1      | {=Tc/user1,user1=CTc/user1}

(1 row)

-- pg_dumpall 

./pg_dumpall > /tmp/dumpall.sql

-- Restore 

./psql -a -f /tmp/dumpall.sql
